I have a Workcenter 3615. It often will show on the screen "toner chip error". I take out the toner cartridge and put it back in. Sometimes the printer will resume printing, sometimes I then get "toner cartridge missing". I again remove the toner and shake it. Sometimes then the printer will work again. Today I have a "toner chip error" and then "toner cartridge missing" errors. I have always used Xerox toners.
I purchased the machine in 2014. I have read to service the machine will be around $300 - should I just replace the machine? Thanks in advance.
