The flashing light could either indicate a cartridge problem or the printer carrier has stalled.
Test the cartridges one by one and do the printer hardware test (refer to the relevant document for your printer) to establish which one is defective. The defective cartridge needs to be changed. To do the hardware test, follow the steps below:
- Switch the printer off.
- Put one sheet of paper into the paper feeder.
- Press and hold the power button and the paper feed button for three seconds until the power light comes on.
- Release both buttons. After three seconds, the printer will start to print. You should obtain a page containing a series of horizontal color lines, and a thick black line below these. All the lines should be solid.
- When the test is complete, switch off the printer. NOTE: If you do not turn off the printer, it will keep on printing this page.
To check if you have a cartridge carrier stall, follow steps below:
- First unplug the printer.
- Move the cartridges to the left by hand. In order to do this, you need to grip the top of the carrier belt (a black/grey belt with cog-like teeth) and pull it towards the right-hand side of the printer.
- Once the cartridges have been moved across, you can clip them out.
- Try to print without the cartridges in the carrier.
- If you no longer have a carrier stall, put the cartridges back into the carrier and clip them into place.
Try to print a document to check if printer is working properly now.
