(the OPC belt has moved to the
right.)
Place something 1 cm thick such as
a book under the right hand side of
the printer as shown in the figure on
the right.
Initialize the printer again and then
measure the gap on the OPC belt
cartridge. If the gap is in the range of
5 ± 2 mm, the printer is installed
correctly.
ii) When the gap is less than 3 mm;
(the OPC belt has moved to the left.)
Place something 1 cm thick such as
a book under the left hand side of the
printer as shown in the figure on the
right.
Initialize the printer again and then
measure the gap on the OPC belt
cartridge. If the gap is in the range of
5 ± 2 mm, the printer is installed
correctly.
Note:
• Place the book or other object 1 cm thick under the printer metal frame as shown in
the figures above. Even if the Lower Tray unit is installed onto the printer, the book
should be positioned in the same position.
• If you have a spirit level, put it on the output tray and install the printer as level as
possible referring to the level.
• The surface that the printer is placed on should have its level corrected properly.
• The temporary action with a 1 cm thick object should only be used to determine the
correct leveling action required and should not be used as a permanent solution.
