Why is my Epson 710 printing everything in pink?

SOURCE: Black ink print failure after cartridge replaced

The Edge, -Clean the electrical contacts on the printer where the cartridge connects with alcohol. After it dries clean the same contacts with a regular pink, non-abrasive pencil eraser making sure you remove all the debris when done. -Its also possible there is an air bubble preventing the flow of ink. You can try inserting a full cartridge of ink in the printer and letting it sit overnight then running a nozzle clean job or two. Another alternative if you have a syringe you may want to try gently forcing ink into it. If you?re really desperate you can try drilling a small hole into the cartridge to give gravity feeding a hand. BE WARNED the air hole will let ink flow pretty well and you run the chance of making a mess. Before you pull the cartridge out of the printer make sure you cover the hole with tape so the ink doesn?t make even more mess. -Check the cartridge alignment making sure the contacts are mating to the printer. -If it still doesn?t work I would try cleaning your nozzles. Even though I doubt you have clogged nozzles its worth a try because of the following: If you search the Internet you?ll find that this specific model is know for failing to print some or all colors after about 1 ½ to 2 years of use, even with Epson inks. Most of the posts I?ve seen blame it on clogged nozzles but I suspect a good number of them, like yours, have another explanation for their failure. Ink jet printers use resistors to create heat to create a bubble in the ink to eject it out of the nozzle (Bubble jet) or in the case of Epson, vibrating crystals push ink into and out of the nozzles (piezoelectric). We?ve already cleaned the electrical contacts and cleaned the nozzles so what remain are defective nozzles, short between the nozzle and the controller board or a defective controller board. Since the printer is only worth 1 or 2 hundred dollars repairs at a shop or buying these repair parts can easily exceed ½ its cost. Hope something here works for you, I just recently had to toss a great printer too. Let us know what happens and please don?t forget to rate the posting.

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.

When you run the nozzel check, do each of the colors print out right, or just the magenta ones?
