White stripes evident each time the printer is started up from cold
I have a Phaser 850 but I am sure it is not too different from the 860.
Each time it starts up it has white stripes vertically on the printed pages and I have to select the Elinate White Stripes option on teh Help menu usually at least two tiimes, sometimes three.
Surely this is not normal?
I would have thought that the startup (which includes a cleaning routine I think) should sort this, esepcially as it takes up to 15 minutes to warm up ready for use.
I have replaced the light blue maintenance tray roller recently and this doesn't see to have had any effect on the problem
One it is warmed up and has had the EWS routine run two or three times it is fine
How can I sort this please?

Re: White stripes evident each time the printer is...
Those solid ink machines are designed to be left on 24 hours a day, 7 days a week. (it uses about $20 in ink to turn on each time)
When turned off the printhead nozzles can get clogged up with dry ink, which causes white stripes. Running the eliminate light stripes routine purges the printhead (using another $10 or $12 in ink). When it becomes a continuous problem the printhead needs to be replaced....very expensive and time to get a new printer !

19.003:48 is the error code 64663is the number of pages the unit has printed. the error indicates a power difference of +- 20% when trying to drive the printhead. The issue is the Electronics Module (System logic and power) or the Wave Amplifier (Printhead Controller). Both of the parts are fairly easy to replace. If it is the wave amp it is a somewhat affordable part.if it is the EM you should replace the printer. It isn't worth the fix.
Have you tried using the jet substitution instead of cleaning every time. We used to do that till we had 5 or 6 weak jets then run the cleaning and if they have all recovered turn off the jet substitution..
You should do a basic clean from the control panel menu a few times, do a light stripes page and see what jets are bad, and if needed try substituting the bad jets. If after trying cleaning and substituting you still see light stripes you will need to replace the printhead. Here are 2 videos I made that show you how to do all of that. Good luck, hope this helps!
Hope that this helps.
Most likely cause is a failed drum heater. The head to drum gap
should only be checked or adjusted on the Phaser 840. The
Phaser 850 and 860 have a pre-adjusted head.
If I remember correctly, disconnect the print cable, then reboot the machine. I saw that problem once and its been a while, but I do believe thats how I finally got it to stop. Then clear out the print queue.
What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem. You can try googling. Phaser printer print heads or phaser printheads. There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head. Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads. Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP. The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.
When you go into the eliminate light stripes there is also a mode called Jet Substitution. You can sometimes bypass the bad jets.
If that does not work then the print head will most likely need to be replaced.
You can replace the printer for less than the cost of a print head normally..
