yellow not printing by jnabney (4/12/05 2:51 AM) reply + / -
I have done over 10 head cleanings, uninstalled my printer from the add/remove programs, downloaded new printer drivers from the Epson Web site and still cannot print yellow.
Please advise.
Many thanks.

jnabney: It could be as simple as a bad or expired ink cartridge, or possibly even a clogged or failing Print Head Assembly. Unfortunatly, there's no way to actually know with the information you have given us. It would help us to know just what make and model of printer that you have. That way someone that may actually be framiliar with your particular printer, might be able to help you further [example: I help out on the Epson Printer questions & problems]...Denny Conway

Sorry I thought I was at the Epson forum... My printer is an Epson Stylus Photo 890. I have changed the cartridge and executed the cleaning process ten times. I still get the same result.
Following information I saw on the forum, I have deleted the printer, downloaded current drivers from the Epson web site and re-installed the printer. Then re-performed the above tasks with the same result....no yellow.
I am running Windows XP Pro SP 2.
If you require further information, I will be pleased to provide it.
Many thanks.

Janet: It's of course even possible that you may even have an actual hardware/parts problem, such as a failing Printhead Assembly. However, normally the most common problem is clogging of the printhead nozzles, especially if you were actually using non-epson ink cartridges. You might want to try using the "Epson Stylus Head Cleaning Solution", available through fixyourownprinter.com, at http://www.fixyourownprinter.com/kits/epson , but it will only help, if there is an actual clogged printhead assembly. When it opens, click-on "Epson Stylus Head Cleaning Solution" thats listed for your particular printer. The epson solution sells for around $10.00 plus shipping. It includes a syringe and some epson printhead cleaning solution, which is designed to dissolve most clogs, especially if you were using epson inks. This is the same chemical used by epson in their service department. You can try it if you want to and see if you can get the printhead nozzles to open up again, but that will only help if they are actually clogged. It was basically designed by Epson Company for use on their older models of ink jet printers, but people have been using it on the newer models, with success reported. IF YOU DECIDE TO, TRY THE "EPSON STYLUS HEAD CLEANING SOLUTION", JUST REMEMBER: The nozzles inside the printhead assembly can be easily damaged by using to much force on the plunger of the syringe. Damage can even occur when you are using the epson stylus head cleaning solution method, if you actually try to force the fluid thru the nozzle. To much force/pressure can damage the little tubes inside the nozzle assembly and then it will never work again. One individual printhead nozzle is so tiny, that it will not accept a human hair. You can see why they can get clogged so easily, or even why the nozzles can be so easily damaged. The correct method is to use the syringe to add the fluid into the nozzle and then leave the fluids set inside the nozzle for a day or two, to try and dissolve a possible bad clog. If you remove the Top Cover Assembly, then you can leave the printhead assembly parked in its normal home position, at the far right side. Then any ink & fluids that are purged during the cleaning, will normally travel thru the cleaning station hoses, to the waste ink pads. If you have the "Print Cartridge Holder Assembly", positioned away from the home position, then you will need to slide strips of paper towels or coffee filters under that assembly, to soak up any expelled ink and fluids, or it can get all over. Sometimes you might have to use the fluids several times to be able to dissolve the clog in the printhead nozzles. Sometimes the clog will never dissolve, or it actually damages the nozzles. The longer the clog has been in, the worse it is to remove. Again, if the cleaning fluids don't help, then its generally time to invest in a new printer. In some more expensive printers, you may want to get an estimate to replace the printhead assembly, but as a general rule, its not really economical to do in the smaller epson ink jet style printers. You can generally buy a new small printer cheaper than you can have your old one repaired for. EXAMPLE: The printhead assembly in the "C80" Printer sells for around $120 to $130. There is a REVIEW of the "Printhead Cleaning Solution", as well as general "Printhead Cleaning Instructions", that is available to view at http://www.inkjetprinterhelp.us/EKR.html ...Good Luck!

Dear Denny:
Thank you very much... I have ordered the cleaning solution and am hopeful that it may help? I live on the other side of the world, [London] so I will have to wait for the kit to arrive.
I have also been told to run the head cleaning utility but not to print a nozzle check and to leave the ink resting in the head for 4-5 hours as the ink has a detergent in it which should clean out any clogs. I have done this, but to no avail.
So I am anxious to see if the kit you mentioned will do the trick.
I value your advice and am grateful for your help.
Thanks, jnabney

jnabney...Just to let you know: Runnning the printers "Print Head Cleaning Cycle" & "Nozzle Test", is basically the printer trying to force out the old ink in the tiny nozzles, by flushing it out with new fresh ink. There's really not much actual cleaning being performed. There is a small cleaning blade on most of the older epson printers that wipes off the bottom side of the print head assembly, but does not do any in-depth cleaning or scrubbing. As to the possible clogs: Bad clogs must be dissolved from the inside of the tiny nozzles. It takes a cleaning solution stronger than the actual ink in the cartridges, or even the cleaning solution thats found in cleaning cartridges, to dissolve most clogs. I only recommend using "Distilled Water" or the actual "Epson Print Head Cleaning Solution" to clean those print heads with. Most other cleaning solutions can actually cause possible damage to those print head nozzles. As to the ink itself: To my knowledge, there's no detergent of any kind in Epson Ink Cartridges and there is always ink inside those tiny nozzles. Otherwise they would dry out and that would cause them to clog. In fact, Epson Printers need to be used often, or the ink in those tiny nozzles can actually dry out and cause possible clogs. Using non-epson inks or ink cartridges [generic or third-party inks], is actually the wrong ink formulation and that can also cause possible problems, clogging and even possible damage to the actual print head assemblies...Denny Conway
