SOURCE: Print fading down right hand side

I was able to fix it by taking off the top of the printer. This involved taking off 4 screws on the top of the printer. I then had to disconnect the wires going to the control panel by unhooking them from the right side. I then located a thin rectangular box which I'm assuming houses the laser. I removed this with 4 more screws and turned it over. There was a little metal flap that I moved back and below was the mirror the lasers shoot on before going onto the toner.

In the same spot where I was having fading, I noticed a lot of toner on the mirror, so I cleaned it of, put it back together, and the fading was gone.

This was after I tried a new toner and maintenance kit.

Hope this helps

Your scanner lamp is dirty. Take apart the scanner glass and clean the lamp. (Look for contaminated spots on the scanner lamp).

SOURCE: The Magenta colour on my 2605dn is no longer

A faded magenta on this model is probably a dirty scanner mirror.
The printer design puts a fan in an area that blows magenta toner directly at the laser scanner.
The more toner on the mirror, the more faded the print.
You will need to remove the scanner and clean it.

Want to know how to print with black after my color cartridge runs out on an cannon ip2600 printer

When you click on print icon it goes to the print menu that allows you to select pages, in that menu you should have print options or colour options or something like that, you want to look for an option that allows you to select 'GREYSCALE' this will only use the black ink!

Hi. After using budget ink cartridges, the print quality has been very poor and not printing the correct colours it suppose to. I've performed many print cleaning options but it is still not rectifying...

If the cartridges you're using give you poor results, throw them away cos you don't know what other damage they might be doing.

I'm not saying don't use budget cartridges, just bin them if they don't work properly and get a different brand.

Alternatively, are cheap cartridges worth all this hassle?

Need to use the printer machine in black and white as missing yellow toner waiting for it but machine is blocked and need urgently to print docs. Pls help me

Unfortunatley most printers will not allow you to print if one of the colours are missing or empty.and so you will need the yellow toner to be replaced before you can print. there is a way that sometimes works and that is to remove the toner cartrige and give it a good shake this evenly distributes the toner inside and sometimes make the printer think it has enough toner and allows you to print. As I said this only works sometimes and is not a perfect solution

Xerox Phaser 6250 won't print colour in Windows 7 - despite having latest drivers from xerox, the test page gives Color support: No


I had same problem and it was driving me crazy. Try this one:

Control panel -> Devices and printers -> xerox printer with mouse right click

Printer properties -> Options

From list you'll select configuration and it gives you drop down menu and from menu you need to select your printer.

I didn't try this one yet because more solid ink is still on the way but this gave me all printing options back. Before basic printing mode was selected.

Funny stuff, uh?

With colour output from a Ricoh SP C222SF Aficio I'm getting lines through all colours, from print and photocopy. Do I need to replace toner, or clean something...? Suggestions welcome!

Pull out your toner assys and look at the drums on each the should look clean under this is the belt that transfers all the colors it also should be clean, the last possibility is the fuser these are all maint items. Have you tried to check the maint items? (menu OK machine settings OK Supply info) or Menu OK machine settings OK TB clean.
-Carl, please let me know if this helps.

Go to system setting, under printer setting there's a menu to forced output print or A4/Letter changing, if you can not find it try the key operator program/ admin mode ( default password for admin is admin )

Plotter needs recalibration

You need to enter the service calibrations menu, to do this select the set up menu, once inside the set up menu press the up arrow & enter keys together. This will take you to the service tools menu, from here select service calibrations (printhead alignment and colour calibration are both in this menu). If you still here problems after you have calibrated your machine or the calibration fail replace the printheads.
