No. : DTE-140
1. Trouble shooting diagonal feeding of small size original documents.
1.General: Because the pressure roller stays are attached by insertion hooks in the rear and
screws in the front. As a result, it easily becomes loose, causing the pressure of the
pressure roller to become uneven. When double side feeding of small sized documents
is carried out, diagonal feeding sometimes occurs (diagonal printing). T o alleviate this
problem, mylar has been added to side plate R.
2.Description: Stay mylar has been added to the pressure roller stay insertion holes in side plate R,
preventing the stays from becoming loose.
