Do-it-yourself epson t27 printer repair

DIY printer repair - what you can do at hometo save money on calling a master or sending a printing device to a service center? Not all problems can be solved on your own, but there are things that you can diagnose yourself. However, do not forget that a serious malfunction can be identified and corrected exclusively by the hands of a specialist with extensive experience and specialized tools for carrying out the corresponding work. Repair of printers by service center engineers YauzaOrgService guarantees high quality and speed of service delivery without overpayments. But what will it be possible to reveal at home?

• The most common cause of printer breakdown, whether Canon, HP, Epson, Oki, Samsung, Ricoh, Brother or Xerox, is to clean the machine irregularly. In simple words, it is dirt. It often leads to imbalance of the case, noise appears during operation, or paper picking stops. That is why it is recommended to clean the printing device at regular intervals and only when the equipment is off. But you need to know about the prohibition of the use of alcohol - for wiping we take only ordinary distilled water, a new sponge and cotton swabs.

• We check the correctness of operation: the printer must be plugged in, the tray is pushed in firmly to the very end, the sheet guides are set, the cartridges are correctly installed and there is no jam of foreign objects in the machine.

• Do not be afraid to inspect the inside of the equipment for paper debris or scraps, toner spills, plaster, sand, or water.

• Check the cartridge is full, if it has run out.

• If printer malfunctions are displayed as errors on the computer monitor, be sure to write down the code, number, or information on the screen for transmission to the wizard.

• Pay attention to the print quality of documents, whether there are additional streaks or spots, what color they are.

• Track the frequency of paper chewing.

• Listen for extraneous sounds, crackles, noises when printing.

Having considered all the above nuances, which often lead to the stoppage of the printer's functioning, you can speed up the process of correcting a malfunction, replace the repair procedure with preventive maintenance and save money on a specialist visit. Evaluation of the state of the equipment operability, the exact formulation of the problem and the listing of the problems that have appeared will allow the foreman to respond to the request as quickly as possible, since he will present the amount of work in advance. If this is not a serious breakdown and the situation allows you to repair parts, replace components or restore work quickly - printer repair can be carried out even at the diagnostic stage. By calling the phone number or sending an application through the website YauzaOrgService - assistance will be provided with the provision of a guarantee for all types of operations and services performed.

Many have EPSON inkjet printers at home. During the operation of printers, malfunctions of varying complexity can occur. Of course, this article will not solve all the problems, but it will allow you to objectively assess your strengths and capabilities when repairing a printer. Allows you to set the direction of troubleshooting.

Let's start with inkjet theory.

Epson applied the principle of squeezing out a drop of ink; as a piston, the property of a piezoelectric element is used to change its shape when voltage is applied to it.

The advantage of such printing is the ability to place the nozzles very close to each other and get a high print resolution.Disadvantages - very high requirements for the ink used (for fluidity, dispersion of the dye, drying time); as a result, the cost of this ink is quite high. Therefore, users try to use ink from other manufacturers.

To reduce the cost of ink, Epson's competitors are making the technology cheaper; perhaps the parameters cannot be reproduced ("know-how", however!). And the result is "on the face", or rather - in the head (printer): the nozzles are clogged, the ink itself dries up.

Now let's move on to an overview of tips and tricks gleaned from StartCopy.

First advice - the use of an ultrasonic bath for washing the head. I did not use it myself, but here are the conclusions I made from the tips for use: first, you need to find or buy a bath somewhere, then experiment with the printer head (immersion depth, soaking time, liquid composition), and if you have one printer (say, home ), then any unsuccessful experiment leads to the failure of the head (and the printer) permanently. Should I bother ?!

Second tip - washing the head under pressure.

The technique is as follows: fill a syringe with liquid for cleansing the head and, gently pressing on the piston, try to pierce the nozzles. If the nozzles are not very dry, then this method will help; and if not, the piezoelectric elements will burst, and - goodbye, head!

Method three , personally tested. based on the use of the method recommended by the manufacturer itself: using the pump, which is available on all Epson printers.

To begin with, we stock up on a sufficient amount of liquid for flushing the heads (0.5-1 l), since the larger the packaging, the cheaper the unit of liquid volume is. Then we partially disassemble the printer so that you can get to the parking lot. We make the head move to the side and drip the liquid onto the foam rubber in the parking lot, put everything back in place and leave it to soak for several hours. It is better to return the head when the printer is off, so that the pump does not pump out the flushing liquid - it's too early.

Then we turn on the printer and let it carry out a cleaning cycle. We print a control sheet. If the result is unsatisfactory, we prepare several syringes (preferably a smaller one - by 2 ml) and saw off the upper part of one syringe. We fill the syringe with foam rubber, remove the cartridge and put this syringe on the ink intake instead of the cartridge. Pour liquid into the syringe and give the printer several commands for pumping; you can even print; then we return the cartridges to their place.

I sometimes pour liquid into the cartridge itself (2-3 ml., Closer to the intake) - the ink in the cartridge also dries up. Then I give the command to pump with this ink - and that's it, in 90% of cases this technology helps.

If the described measures still did not help, then we take off the head and try to rinse it with a syringe, but we do not focus on squeezing out dried ink (what the pump did), but on sucking ink from the head. If a result appears - say, 70% of the nozzles are printing - we buy original ink: they must finally clean up what we did not succeed in.

And only then we put in compatible ink - and save, save, save (until the problems appear again).

Unfortunately, the original ink is not a panacea for all ills: it dries in the nozzles as well as compatible ones - for example, went on vacation, and hello to the head; the problem is assured for you.

And now about the sad thing: the developers at Epson are not asleep, they have launched polymer ink into production, which does not seem to be washed off and does not fade. But if they have dried up in your head, how do you order them to be picked out from there?

Separately - about the reset of the sump overflow counter (in the everyday life of "diapers").

I recommend this procedure to start and finish all work; and if necessary, then change the filler itself in the sump.

What to use as a filler? The scope for imagination is the largest: from the original to medical cotton wool.

Well, if you have touched the diaper, then it makes sense to talk about the prevention of the printer as a whole.

Prevention of the mechanics of an inkjet printer is not much different from the prevention of a dot matrix; only here, perhaps, there is more dirt - this is spilled or splashed ink, and paper dust. All together gives "excellent" result: dirt is coked in the mechanics up to the complete failure of the printer.

Regarding the selection of lubricant for the guide, I will say the following: ideally, you need a lubricant for precision mechanics (watch oil); earlier in the hardware stores they sold sewing machine oil - it will also work. Now it is possible to buy gun oil as well.

Felt rings or gaskets in the guides need to be replaced or washed (depending on the model).

I will separately say about the parking space of the head. I already mentioned foam rubber in the parking lot above, but be sure to pay attention to the rubber band that is pressed against the head: it should not be dirty so that the clamp is as tight as possible - then, during long-term storage, the ink will dry up later.

Particular attention is paid to the knife that cleans the head: there should also be no dried ink there.

When building a country house, priority is usually given to interior decoration, and the arrangement of the site is sometimes postponed "for later." However, after trying to get from the garage to the house in the dark and stumbling several times along the way, the owner usually comes to the exit that installing outdoor lighting is not something worth saving on. Moreover, this lighting should be well thought out, planned and functional - there is clearly not enough light from the windows of the house or a lonely lamp above the porch. More details ...

It is unsafe to neglect poor electrical wiring in the house, and especially if it is wooden! If you lose contact in the outlet, the light "flickers", interference periodically appears on the TV screen, wheezing appears in the receiver, then you should worry about checking your wiring. Perhaps somewhere there is a bad contact and as a result of this, heating and ...

Frequent breakdown of game consoles is a break in the power cord at the base of the connector, as well as unsoldering or breaking off the connector itself that feeds the console. In one case or another, the game console does not receive power from the source and starts "freezing" or turns off completely. More details ...

The Epson T-27 printer served faithfully for about 5 years, refillable cartridges, did not print that much, not that little. a couple of documents every day.
Recently, during printing, sometimes a sound is heard, a short one, and the printing of text on a sheet of paper seems to shift, or rather - superimposed, one line on top of another.
Can you please tell me, is it something mechanical or something in electronics? can anyone have met with such a malfunction.

I wanted to insert a scan of a sheet with text overlay here, but something doesn't work. a :" . use third-party services,
uploading photos is still disabled for security reasons ”, I don’t have photos on third-party servers, all photos are in folders on my computer.

No, the text does not double, but as if it printed a couple of lines, and then as they held a sheet of paper inside and printed a new line on the previous line.

Well, the paint is 2 years old, I constantly refill the cartridges as needed, there were no problems. Before that, there was another set of paint, I spent 3 years, there were no problems either.
Everything prints colors.

Epson is one of the three world leaders in the production of printers. Thanks to the use of high-quality materials in the creation of equipment, as well as good warranty conditions, even ten-year-old devices still effectively fulfill their duties. But even high-quality equipment sometimes fails.But is it possible and how to carry out an easy DIY repair of Epson printers?

When buying printers from Epson, you need to take into account that these devices have a number of features that mislead the average user:

Printers have a printed page counter that must be reset periodically;

A special chip is installed on the cartridges, which sends information about the amount of ink used. Because of this chip, a lot of problems arise, since quite often the ink can still remain, but the printer refuses to print.

Since there are really a large number of faults, we will consider those that occur most often and catch users at the worst possible moment.

If you have not used the printer for several months, and when you turn it on, you find that it either does not print at all and gives an error, or skips certain sections. In this case, flush the nozzle with a special flushing agent or distilled water. This is done in the following way:

1. First, open the printer and move the cartridge unit aside.
2. Under it is a special container - an inkwell (colloquial: "diaper"). We fill the container to the brim with a syringe.
3. We return the cartridge block to its place and leave it to soak for at least two hours.
4. After the specified time, we start a test print and if the printer does not skip certain sections, then you have coped with the task.
5. If, however, gaps still remain during printing, but their size has become much smaller, we repeat the procedure several more times.

If the printer has been out of work for more than a couple of months, then this method most likely will not help. To fix this type of malfunction, we take the following steps:

1. We find a shallow container and pour distilled liquid into it for washing. We calculate its level so that it does not reach the height of the chip, but completely covers the nozzle. We leave in this state for 2-3 hours.
2. After the specified time has elapsed, we take out the cartridge and run the test print several times. You need to do this until the colors on the paper are saturated.

If this method did not bring visible results in servicing the Epson printer, then you will have to buy a new cartridge.

This error can manifest itself right during printing. There are two possible problems here: the ink is out, or the chip has given a signal that the maximum number of pages has been printed.

In the first situation, you will either have to buy a set of cartridges again, or refill the old ones. But when refueling, we will face restrictions imposed by the manufacturer directly.

Standard cartridges that come with Epson printers are not intended for refilling, and they are designed for a strictly defined number of printed pages. It turns out that in fact there is paint, but the program (or indicator) shows that it is not.

There are many ways to get around the restrictions:

• use a microprogrammer that resets the chip counters;
• Purchase a set of refillable cartridges in advance from a third-party manufacturer;
• purchase a replacement set of reusable chips, the counters of which are automatically reset when the limit is reached.
• use CISS systems.

In practice, all methods are equally good, but the most comfortable is the use of CISS (continuous ink supply system), since there is no need to remove the cartridge from the system for refilling.

Self-repair of an Epson printer for the average user is complicated by many subtleties that the manufacturer has provided in order to increase its income. But it is quite possible. The main thing in solving a problem is to show as much patience as possible.

Epson inkjet printers are prone to frequent clogs - this is an undeniable fact.Suspensions in ink, air bubbles, excessive vaporization, dust from paper and many more subtle and annoying reasons can become the reason. One of them, by the way, is the main one, is a long idle time of the printer on the table.

Before starting any printing, if you are interested in a normal result, you need to check the operation of the printer's print head using a nozzle pattern. Such a template is printed out by standard means through the driver, or by pressing certain buttons (see the instructions for the printer) on the printer case.

Ready-to-print printer:

And in this case, there are obvious blockages in the print head of the printer - a disease of any Epson inkjet model:

At different times, different Epson models had different templates: from thin lines, from thick lines, large, small, even with solid colored squares, but the meaning of such a check has not changed - if you see gaps and spaces, then the printer is clogged. Such blockages will appear on prints with colored stripes across the image or excessive graininess, in general, parasitic information that spoils the appearance of the print.

As for the quality of ink, native ink from Epson, especially in the first year of operation, clogs the printer much less than analogues. This is also a fact, although third-party manufacturers tend to improve the quality of their product, and decent ink samples come across on the market, but no one has "cracked" Epson's secret yet.

But in reality, the printer still clogs up, and since we are more often dealing with CISS and analog ink, then we will encounter cleaning the print head more often.

The print head of the printer on the carriage and the airborne CISS:

The simplest blockage is the absence of a few stripes in the check pattern. This can be cured with one or two cleanings. If the printer is aged, then a “walking” blockage is possible - that is, after cleaning, the segments appear on the template, and immediately disappear after printing. In this case, you need to charge the cartridges or CISS to capacity and let it stand for a significant period. It helps in 90% of cases. But before that, you need to make sure that the fittings on the print head (where the cartridges are inserted) are clean, free of dirt scale.

It is impossible to clean (that is, through the standard cleaning function) for a long time. Three, four, but five times is already the limit. Further, unwanted temperature processes will begin to occur in the head, and then you will definitely have to put the printer aside for a week.

It makes sense for specific disappearances of colors after one or two cleaning runs to start up just such a printout at the highest quality.

For grayscale (i.e. to restore black):

The type of paper specified in the driver is only important for the driver to allow setting the maximum dpi. In this case, you can also print on ordinary 80 g / m2 paper at full width.

There are a few things to pay attention to when cleaning.
The entire route of the printhead must be kept clean:

The paralon should not bump up, and of course there should be no debris. The photo shows a sample of a rather dirty printer, and of course the percentage of blockages is higher. It is recommended to arrange for the waste ink to be discharged outside, and not into the internal diaper.

Another important point is the parking space (the picture shows a very dirty sample):

This is a fundamentally important part of the printer. On such a platform, movable with springs and sensors, in rest mode, the printer parks the print head. Naturally, over time, what you will not find there - hair, dust, lumps, even animal hair. That is, the cleanliness in this part of the printer must also be monitored and very carefully wiped with an alcohol solution. It is possible to collect dirt from the fittings and planting with a syringe, drawing in the sewage. But a fleece on a stick can leave a parasitic nap, so be careful with this.

Cleaning with flushing fluids
There are special fluids available for flushing the printheads. Previously, they were replaced by a weak solution of ammonia, now the heads have become technologically more complicated, and it makes sense to insure yourself by buying such a liquid:

The use of "flushing" does not cause any difficulties.The main thing is to choose the right type of ink for your printer. Old Epsons were generally cleaned by everyone, except of course alcohol (too aggressive environment).
The flushing liquid is poured into the cartridge, and let the printer settle overnight. In very difficult cases, clean through a regular cleaning, and also print color prints at the highest resolution. You can dilute the ink and liquid with this liquid if you need to preserve the printer for a long time.

In severe cases, it is better to remove the head and immerse its bottom in a container with flushing liquid.

Purge the print head
It makes sense to use a blower when nothing helps - the check template displays a blank sheet, and there is no hope of getting at least some lines on it.

You can blow it out with dropper hoses or gently with a syringe. To supply air carefully, without saliva and water - there is a very high risk, especially in later models, to permanently kill the printer head.

From time to time, printer owners encounter malfunctions. Most people have independently acquired personal experience in eliminating the minor flaws of such a device. As practice shows, a frequent reason for the unwillingness of the printer to work may be a software failure or a minor malfunction in the mechanical part, which can be eliminated independently, without seeking help from a specialist.

Let's consider the probable causes of malfunctions and how to eliminate them on our own, without resorting to the help of another person.

The device of printers such as HP, Canon, Epson, Samsung, Sharp, Ricoh is fundamentally the same. Therefore, we will consider several reasons that are found on all printing devices:

1. After the printer gave you the information about the error, first of all, check the presence of paper in the loading tray, whether the paper is jammed, the presence of toner in the cartridge, whether all the covers on the printer are well closed and, of course, the connection to the network and to the PC.
2. A common problem that you may not be shown is a software glitch.
3. One of the most common malfunctions is contamination of the mechanical parts of the device. First of all, you need to disconnect the printer from the power supply, open the top cover where the cartridge is located, take it out and visually inspect both the cartridge itself and the mechanisms in the field of view. In case of contamination of the mechanism, you just need to wipe it off with cotton napkins, slightly moistened with water. In hard-to-reach places, cotton swabs will come to the rescue.

Important! In no case should you use detergents and liquids containing alcohol.

In addition to all of the above, listen to the operation of your device. Are there any extraneous noises coming from it? If you hear them, this could be a signal that the gears that activate the printing mechanism are out of order. In most cases, they are made of plastic.

Below we will consider how to make repairs using the example of an HP LaserJet 1100 printer. This manual will also be useful for repairing Canon, Samsung and Epson printers.

Suppose the thermal film is damaged during printing with a paper clip on the sheet. For repairs, you need a small set of tools:

• crosshead screwdriver;
• flat thin screwdriver;
• pliers with long jaws;
• wet wipes or cotton-dampened pads.

Having prepared the necessary tool, we proceed to repair the device:
