Epson Epson Stylus Photo 900

Problem with Epson Stylus 900

I have two 900 printers, each with a problem. I'd appreciate any advice you could provide as to the possible cause and the solution.

Printer #1:

Looking at a nozzle test print, there appears to be black ink (or possibly bule ink) appearing on the bottom row of the yellow ink test portion (the darker ink begins about one third of the way from the left of the bottom row all the way to the far right of the bottom row). All other rows of the yellow ink test portion look fine.

We run several cleaning cycles and the problem goes away, but after printing a couple of pages (that happen to use lots of yellow ink) the problem resumes. We've done this maybe a dozen times -- clean heads, run prints, problem returns, repeat...)

Then we tried the Epson Head Cleaning Solution we purchased from FixYourOwnPrinter, leaving it overnight with the heads parked over the foam pad that we saturated with the cleaning solution. Again, same problem -- it works for a short time, then the darker ink appears on the bottom row of the yellow.

Suggestions?

Printer #2:

Also an Epson Stylus 900. This printer has problems printing a very narrow vertical line with black ink. It's noticable when I print a standard head test print -- the vertical black lines on the far left side of the black text bars are "whispy" -- that is, in some placesm they seem to fan out just a bit to the left or right, instead of being straight up and down all they way through. We ran the vertical alignment several times, but the problem persists -- and in fact, running the vertical alignment test shows this problem in spades. It's hard to describe, but perhaps "wavy" is another term that might describe this.

I could email someone an example of this if it would help.

Any suggestions to both/either of these problems would be gratefully appreciated.

Best regards,

Brad...PRINTER #1: That cleaning solution will usually only help if there is actually a clog. That does not seem to be the case with this printer. As the problem seems to clear up, at least for awhile after running the printhead cleaning cycles, I'm guessing that the underside areas of the actual printheads are probably really dirty and could be causing your printing problems. Its possible that your problem is being caused by a build-up of dust, dirt, lint and hair that sticks to the wet ink on the bottom side and backside areas of the printhead assembly. That build-up acts like a small paint brush and can transfer wet ink to the paper as the printhead assembly is moving back-n-forth during the printing process. When that build-up dries around the ends of the printhead nozzles, it can also cause the nozzles to fire at an angle, causing what looks like tiny lines to appear on the paper or nozzle test. Sometimes that build-up simply smears the wet ink already on the paper, from the printing process, or can cause other printing related problems. Once those two areas are thoughly cleaned, the problem will normally go away, unless its actually being caused by a hardware/parts problem [such as a failing Printhead Assembly or Main Board Assembly]. Check for a couple of e-mails from me that should help in that area, in case you want to do the cleaning and at least eliminate that possibility...PRINTER #2: Its also possible that the same area on this printer, could be causing problems for you, as possibly with printer #1. Sometimes when that build-up gets bad enough, it acts like a small paint brush and transfers wet ink to those small white or grey relay type rollers, that the paper passes under, just prior to going under the Print Head Assembly, during the actual printing process. Those small rollers then act like tiny paint rollers and roll the wet ink onto the paper as it passes by. Thats the most common problem with verticle lines being printed out on the paper. Again, once those two areas are thoughly cleaned and then the small rollers are also cleaned, the problem will normally go away. Check for a couple of e-mails from me that should help in that area, in case you want to do the cleaning and at least eliminate that possibility...Good Luck! Denny Conway
