Question about Tektronix Phaser 860 Thermal Printer

1 Answer

White stripes evident each time the printer is started up from cold

Hi 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? Thanks David

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 !

Phaser 8500 error code 19,003.48:64663

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.

Makes a white strip in the left side of paper

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!

I have light vertical stripes on a dark picture and dark stripes on lighter colored pirctures. I have cleaned the head about 15 times and it is worse now than before. I am wasting ink and getting nowhere....

Have you checked the maintenance kit? Is the white roller badly contaminated? The mylar blade dirty?
If that is ok, then you may have a bad print head.

Printer error on Tektronix Phaser 860dp

Hi juniorgona:

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.

Hope that this helps.

Xerox Phaser 850. Unexpected repeat printing

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.

I have a Xerox Phaser 8400 with image problems. After power up it prints a Startup Page - That page is black text which faded and slightly distorted in some areas and in areas that are in Color only...

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.

Xerox Phaser 8400N Printing Stripes

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..
