In this document, package delivery slips means 5- to 13-part 
form slips that have a thickness of 0.3 – 0.78 mm. The multipart 
copying capability and printing accuracy for package delivery 
slips, which depend on each form’s thickness and middle-part 
quality (including thickness), are not assured. Slips that are non-
uniform in thickness must not be used.

PAPER
As recycled paper tends to generate more paper dust than 
normal paper, clean the printer on a shorter cleaning cycle than 
that recommended in the User’s Guide.
As recycled paper may be easily affected by humidity, do not use 
recycled paper in very humid environments.
