Troubleshooter

As the majority of Canon Laser Printers have the drum unit built in to the Toner Cartridge this fortunately makes troubleshooting a little easier as there are only a limited number of consumables to replace. 

If the print that you were receiving from your old cartridge was perfect right up until the point where the printer requested a new toner then after replacing it the pages produced instantly looked poor, it is incredibly likely the toner cartridge is at fault however if your machine is a colour printer then it may be worth printing out a test page to ensure that it is definitely the cartridge that you have just replaced is defintely the one causing the problem.  Such a sheet can be located by clicking here - Simply printing out this page should easily confirm which colour is causing the issue.

Once the offending colour has been established please try the following:

- Remove the cartridge from the printer and gently rock from side to side; often toner can 'clump' in to one end of the cartridge and performing this process can distribute it evenly throughout the toner cartridge.
- Print a dozen pages or so with the cartridge to ensure that the toner rollers have been suitably covered and that the photoconductor of the drum has been given a chance to establish a static charge.

 

If the poor print continues please it is possible that you have a faulty cartridge so please contact us so that we can potentially perform further troubleshooting before replacing the cartridge if necessary.
