[Note 1] Replacement reference: Replace according to each paper feed counter value.
MX-LCX4 Paper feed tray 1, 2, 3: 200K or 1 year Torque limiter: 800K
(NOTE) Paper feed section roller life
Each roller life is as shown on the left. When, therefore, a certain paper feed unit is excessively used, its life may be expired before the mainte-
nance timing.
Actually, however, different sizes of paper are used with different paper feed trays, and it is quite rare that the roller replacement must be made
before the maintenance timing.
If a certain size of paper must be heavily used, set different paper feed trays for that paper size. This information must be explained to the user.
When servicing, check the use frequency of each paper feed tray, and replace the rollers as needed.
When cleaning the roller, it is advisable to use a cloth with a small quantity of water.
The friction level is smaller in the order of the paper pick-up roller, the paper feed roller, and the separation roller.
