1. Shut down the Acer laptop, unplug the AC power adapter and all extensive devices.
2. Remove the battery pack from the battery tray that is at the bottom of the screen.
3. Open the display panel as far as You can open it.

Had experienced the same problem with a Phaser 8560DN, the only solution for that is to replace the panel. You can buy one off Ebay for $50: http://cgi.ebay.com/Xerox-Phaser-8500-8550-8560-LCD-Control-Panel-Display-/110649342908?pt=LH_DefaultDomain_0&hash=item19c336fbbc

You can call 1-800-835-6100 and they will send you a new display. There is a known problem with those on that machine.

Hi there
The onlty thing I can find close to this is.
Acording to the manual its a ink loader error like your loading the wrong type of ink like the puzzles pieces arent matching and hitting the sensor flags right. Yours by the 8 is referring to the black ink. Anyway go to troubleshooting on the control panel. then to service tools. when in service tools press and hold the up arrow while still pressing the up arrow press the down arrow. the display should say hidden menus. go to diagnostic mode press enter go to funtion menu. then go to clear ISC fault and enter. ISC=ink stick count fault. I hope that helps. Just to let you know Ive had nothing but problems with third party ink and once its in the system its hard to get out so I would watch what im doing with my expensive equipment

Even if your printer's front control panel display has not gone bad yet, it could only be a matter of time.

If your printer has never had its control panel display replaced, you can get a free replacement from Xerox, even if the printer is out of warranty. Just call 877-571-7765 with the serial number of your printer.

I think this is due to a known defect from the factory for many of these panels having a bad soder weld which eventually causes issues with the panel, even if not apparent at first. That was the case I had. Just one day out of the blue my panel went blank, some days its lit with no display others the display is upside down or reading gibberish other times it seems to work fine. I tried looking for a bad soder myself but couldn't find it then later found out there was a soder issue via another post on this site and they will replace this panel free of charge.

This model of printer has a known fault with the LCD panel.

Contact xerox in your country, who will arrange to have a replacement front panel sent out to you to install

It sounds like the display panel has gone bad. Possibly the text is garbled or only half shows up??

If you contact Xerox and tell them, I believe they will send you a replacement display panel - even if your printer is no longer under warranty -- IF your printer has never been sent a replacement display.

I've had this happen on several of these printers - I believe they know there is an issue with the display panels, which is why they are sending replacements for free.

I find the easiest way to contact them is to go through the support section at xerox.com and search for that error, then hit contact us at the bottom of the page. It'll ask for your contact information as well as the serial number of your machine.

I have the same problem with 800x600. I've found that by setting the refresh rate to 56 Hz, I can get the games to play. For instance Age-Of-Empires II only works with this method. My old monitor worked fine, and this works at 1280x1024.

I called and they are sending me a new one. The number I found for this is 877-571-7765 - You will need your serial number on the insude of the front flat - pull grey handle.

When our control panel went blank last month, Xerox did not offer a free replacement because our printer was out of warranty. Consequently, we ordered one from SparePartsWarehouse.com at the best price we could find - $104.87 plus shipping. The part number for our 8550dp is 848K06551, but these are the compatible part numbers for the "Xerox 8500 Control Panel & Bezel": Compatible Part Numbers: 848K06551, 101E28730, 101E28731, 802K93650, 802K93651, 848K06550, 848K06552. It is easy to replace, instructions are on the Xerox website at http://www.office.xerox.com/printers/color-printers/phaser-8500-8550/sprt-enus.html
Hope this info helps someone, and thank you FixYa for this forum.
