Printer Malfunction PIXMA MG7120

Carol308 — Wed, 19 Dec 2018 02:20:39 GMT

My PIXMA MG7120 printer has recently stopped processing print requests. When I view the print queue there is a stalled print file in the queue, and I get a message that says "Your printer is being used by another computer".

A Google search on that error returns several instances from 2 or 3 years ago but none are clear on how to resolve. At the time (~2016) it was claimed that Canon did not know how to fix, even though it was common enough to generate a number of internet searches for a solution.

We did install and run a Canon Windows app, but with no apparent success.

It is now late in 2018. Has anyone learned how to fix this problem?

Thank you in advance

3. Double-click on the [C:] drive option.

4. Double-click on the WINDOWS folder.

5. Double-click on the [System32] folder.

6. Double-click on the SPOOL folder.

Thank you very much for the detailed instructions.

Unfortunately, this only worked once. After executing the steps listed, I restarted the computer and was able to print a Word document. However, a second print job stalled and I found the same message that "another computer was using the printer".

Would a firmware update help?

Thank you again

Hi Carol308,

You can try updating the firmware on the printer if the firmware has not been updated. Please click HERE for the steps.

If the error returns, please remove the printer from your computer and then click HERE for the MG712 support page and download the MG7100 series MP Drivers Ver. 1.01.

If the print spooler error still continues and the update and reinstall, then I would have to recommend contacting Microsoft. They will be able to troubleshoot the print spooler service on the computer to determine what is causing the error to continue.
