Does the printer have a malfunction? Is it out of paper or toner? Or did something go wrong with your print credit?
Report it to the IT Helpdesk: T 08850-77777 and select option 1, which will put you in touch with Canon.
Mention the printer number PRN-xxx. You can find this number on the sticker on the front of the document feeder.
After the report, turn over the fault card in the plastic sleeve.
