Not printing the display is flashing from the normal information to'put in cartridge'and back

The flashing light could indicate either a communication problem between one of your cartridges and the printer, a short in one of the cartridges, paper jam or the cartridge carrier has stalled. Please follow the steps below to fix the problem:

1. Remove the sheets of paper from the feeder. Make sure there are no foreign objects or debris in the feeder.
2. Open the printer cover and remove both the cartridges.
3. While the cover is open, ensure there are no paper jams and the cartridge carrier is free from obstructions.
4. Close the printer cover.
5. Re-brick your printer. Pull out the power supply, black box where the power cord is plugged in at the back of the printer, and put it back after 30 seconds.
6. When the printer turns on, reinsert one cartridge first.
7. Close the printer cover and check the light status.
8. If light on printer is normal, open the printer cover and reinsert the other cartridge. Check the light status.
9. Replace whichever cartridge is causing the light to flash with a new cartridge. You can also try to insert a different known working cartridge to determine if the other is faulty.
10. Load some paper. Try to print a document again to verify that the problem is fixed.

1. Remove the new print cartridge from the packaging. Gently rock the print cartridge from front to back to distribute the toner evenly. CAUTION: To prevent damage to the print cartridge, hold the print cartridge at each end.
2. Pull the tab and remove all the tape from the print cartridge. Put the tab in the print cartridge box to return for recycling.

1. Make sure you have turned the product on. Press the Power button if it is not lit.
2. Open the print cartridge access door, and then wait until the carriage is idle and silent.
3. Remove the old print cartridge. See the recycling information inside the print cartridge box.
   NOTE: If you cannot remove or install the cartridges even though the power is on, check the product control-panel display for error messages. If none appear, turn off the power and then turn it back on.
