Epson RX620 yellow lines/blocks on page

If switching ink cartridges doesn't work, the next thing to check is your printhead. Make sure your printheads aren't clogged. Most printers have an automatic printhead Click For Full Detail.

Your description of the problem is so vague it would almost be impossible to provide any attempt to resolve this for you. For example - a blob of yellow, patches, lines, missing lines, perhaps a band somewhere across the page or down the page? In any event if it is, say, a thin line running across the page or down the page then that could well be a symptom of a blocked nozzle on the printhead. How often do you use the printer and do you carry out nozzle checks? Is the printer generally in very dry room conditions? So, as an attempt to resolve this for you with only the very limited description you have given, try the following. Set a page to Print to bring the Printer Dialogue Box into view. Click on Preferences and then on the Advanced Tabbed page. On that page, click on Nozzle Check and with a standard sheet of paper in the printer, click to do that check. Examine the output - there will be an example of what it SHOULD look like onscreen - meaning a specific pattern without any breaks in the lines. Even a tiny break indicated some blocking of the nozzle jets. Then use the CLEAN facility offered to clean the nozzles and repeat the nozzle check. That is the most likely cause of your problem. Come back if you still have the problem.

sounds like the printheads need to be replaced. just replacing the ink cartridges won't fix it.

Hello ab_beckwith
Probably you neglected to download the twain driver . You can download it from here :

Not sure if the situation we're in is the same. I have a similar problem, but instead of yellow lines, it is pink lines. printer is Epson RX510. The lines are more prominent if the print quality mode used is best and if the document to be printed requires the affected color. Upon consultation with the printer technician, I was adviced that it is the print head which has a problem, and changing it is costly and the repair duration even depends on parts availability. With that, I just decided to use the printer just as is. Hope this info helps.

the glossy paper you are using (hp) is smearing the ink... there is now ink on the feed rollers and you need to get in there and clean it all up with alcohol...also run epson matt paper for a few prints to get the color to lay down ..good luck

The epson printer RX 620 only prints partially for my photo while I want the whole picture. How do I get it to print the whole thing instead of it printing it partially?

sounds lke your yellow nozzle not working properly...had same issue on lexmark printer, ended up geting this epson...learnt from my mistakes...perhaps it ran dry? or you left the yellow cartridge out longer than the rest....only you might know what happened

try this :

first clear the print queue
then uninstall - reboot - -reinstall the driver

Hi,

None of these answers are accurate.  I know precisely what your problem is, and you aren't going to like what I have to say.  What you are experiencing will happen eventually to every Epson printer and there is nothing you can do about it other than to buy a new printer.  I have an Epson Stylus Photo 895 ( a 500 dollar printer in its day), which has the same issue.  I am just waiting for my ink cartridges to run out in order to buy a new one.

Endless research on google has turned up that there is no solution to this problem.  The issue you are having is with the Epson print head, which uses piezo technology.  What that means is that unlike HP or Canon printers which are thermal, piezo uses a small piezoelectrical cell to force ink out of the chamber.  It has advantages over thermal in that thermal requires a precise temperature to get ink on the page (what actually happens is that ink is heated, it forms a bubble, and the bubble bursts onto the page, hence the name BubbleJet).  Therefore, the ink has to have fairly precise thermal ink properties making it more expensive to manufacture.  Also, the ink on a BubbleJet (or HP) is wetter when it hits the page, and since the ink is heat resistant or order to properly form the bubble, the printer needs to incorporate a fast drying technology which consumes more energy.  The massive advantage of thermal is that the print head is on the cartridge, not on the printer itself; change your cartridges, get a brand new print head.  It makes cartridges more expensive, but reduces problems such as what you are experiencing.

Piezo on the other hand, always shoot ink through the same print head.  Once the head become damaged over time, the piezoelectric cell is no longer accurately pushing out the ink, and there is nothing you can do about it.  If you are lucky, it is only dried ink in the print head, but I can almost guarantee you that it is not.  Dried ink can be cleaned by repeated head cleanings, even manual ones involving rubbing alcohol.  However, I know that those pink lines are caused by the deterioration of the cell, and cannot be fixed.  If if were only dried ink, you wouldn't be limited to just pink lines on the page, you would see other colours.  If the cell is not doing its job, the lines are always pink (often called magenta when you google this problem).  The solution is to acquire a new print head.  Unfortunately, the cost of replacing an Epson print head is IDENTICAL to the cost of a new Epson printer.

So basically you have no choice, you need to buy a new printer.  Were I you, I would purchase a new thermal inkjet printer so that you get a new print head with every cartridge.  Look around before you buy to find out exactly how much the cartridges will cost, and then you will know which brand to buy.  Although piezo *can* make for a cheaper printer at the outset, Epson simply charged what HP and Canon do for their replacement cartridges because that is what people are used to paying, but you really do get more in a thermal inkjet catridge.

Sorry for the bad news,
DD.
