Our client Monrovia City Hall brought a printer Canon ImageRUNNER 2420 with CEXV14 drum toner spots and light print issues.
This is one of the most common printer issues and at one time or another we’ve all sent a print command to the printer, only to be left frustrated and irritated when the printer prints something like this faded printout.
There are many causes of light or faded prints. But in this printer the issue is due to a damaged drum.

If your printer has ink but prints faded or printing too light, we’re going to help you to find out why and help you to fix it and we’ll do it. You don’t need to buy a new printer!
