I have an mf644cdw and continually having quality issues.an amount of toner wipes off the print and I am continually having to clean the fixing assembly.I am using canon toner.How can I fix this or have I bought a lemon?
I have an mf644cdw and want to change the default option from color picture to Custom Settings. Is this possible? I would also like it to automatically Preview. Is this possible?\ Thanks in anticipation.
