Question about Brother MFC 420CN All-In-One InkJet Printer
Brother 420cn - new cartriges machine does show that it is picking it up but will return blank pages when asked to print
Make sure carts are placed well and secured.
press menu then start bk copy then four times arrow-up (tel. index). machine switches to maintenance mode. press 7 then 6 then 4 then start bk copy. machine will refresh ink in tubes and ph and do some cleaning. after that press 7 then 6 then 3 then start bk copy. machine will do a power purge. after that leave mode by pressing 9 then 9. Run a quality test print by pressing ink etc.
If you still cant see any colors the ph has dryed out. If you see some blocks try a manual cleaning (pressing ink shift to cleaning etc.). If the next test print out still is bad the ph is clogged due to generic ink and cant be cleaned anymore. In both way ph needs replacement.
