144 7 Maintenance
7. Place the print cartridge on a flat surface, 
such as on a desk, with the handles facing 
you. Hold the end of the toner seal and 
slowly pull it out from the side of the 
cartridge.
Important
• Make sure to pull the toner seal straight out 
horizontally. If pulled out diagonally, the seal may rip.
• The toner seal will be approximately 70 cm long if 
pulled out properly. If the toner seal was not pulled out 
properly, contact the dealer where you purchased the 
printer.
• When pulling out the toner seal, a small amount of 
toner may spill out. Be careful not to dirty your hands 
or clothes with toner. If toner gets on your hands or 
clothes, wash it off immediately.
• When pulling out the toner seal, do not place the print 
cartridge upright. The seal may not be pulled out 
completely or may rip.
• Installing the print cartridge when the seal is ripped or 
is not completely pulled out can impair print quality, 
resulting in printer failure.
• After pulling out the toner seal, do not shake or bump 
the print cartridge.
8. Hold the print cartridge by the handles as 
shown in the figure. Insert the print 
cartridge into the printer, sliding the 
projections on both sides of the cartridge 
along the arrow labels inside the printer.
Note
• Make sure that the print cartridge is firmly inserted into 
the printer.
Important
• Do not touch any parts inside the printer.
