1
Remove the old DV blade from the DV cover. (Remove the duplex
tape.)

( 0.2). Do not allow extrusion from the edge. Do not allow
covering the inscribed line. The allowable reference shift is within
0.5mm from the inscribed line. Attach the sheet without being
wavy.
3 Remove the base pasteboard from the DV blade.
Note: If the pasteboard is not removed, the drum is scratched.

Attach so that the angle between stirring shaft A and B is 90
degrees.
