    It is a colour printer. Should I replace the toner cartridge. The problem is it was printing something but now nothing is coming -the power comes on as usual the rollers/paper feeders seem to be moving. The red light by the triangle flashes too but all the cartridge lights flash when I try to print.

You should try checking your printer by replacing the cartridge to replace the print cartridge.
click here for instructions on how to do it.

This is a common issue with laser jet printer,

Try running cleaning modes under the service menu on the printer, run 5 back to back. if the issue is still showing, try using a different cartridge and run the cleaning mode again. If you have an old cartridge even if its close to being empty you can do an override on the printer to test the cartridge:
1.press ok
2.use the arrows and navigate to the system set up menu
3. press ok
4. print quality
5. press ok
6. override out
7.press ok and again ok to set

This could also be a build up of toner in the fuser assembly, and you may have to adjust the fuser temperatures in the embedded web server. You can print a blank word document (20 pages) and see if you still see black dots, if you do it is likely to be the fuser, set the driver and printer settings to card stock or heavy in order to heat the fuser more than the usual temp and print 30 blank pages this should resolve the issue. if this does not there could be damage to the ETB or the fuser assembly and servicing of the printer would be required.

take care,

REGARDS

Hello,

First, the fuser assembly may be damaged or at the end of its life. The solution is to replace the fuser assembly. Repairing a fuser assembly is generally not recommended because the fuser is considered a consumable printer part and not worth the time or effort to fix. Second, the toner cartridge may be defective and letting too much toner out at one time. In a black-and-white laser printer, the solution is to replace the toner cartridge.

Take care.

    Hello,

    In a color laser printer, only replace the cartridge that is exhibiting the problem

Spots on paper


Does the pitch of the dots look like it could be caused by the pin wheels on the exit of the paper path?

If so it could be that the wheels have got knocked or sagged and are just touching the print as it exits the machine. Try gently prizing them up out of the way.

Theblack print cartridge is empty or missing. The black-print-cartridgelight is blinking, and then printer stops printing. An error 40208 iswritten to the event log. The printer cannot detect the print cartridgecorrectly. Action
  1. Reinsert or replace the print cartridge.
  2. If the print-cartridge light is still blinking but the Attention light is not on, turn the printer off, and then back on.
  3. If the problem continues, contact HP Customer Care at http://www.hp.com/support/clj2550 or see the flyer that came in the printer box for other contact information.

Still using color toner when printing in black


Check the black toner cartridge. Most printers that use multiple cartridges will use the black cartridge as long as it has toner in it but will then start using the color toner to do the black/grayscale when the black cartridge is empty.
