Chapter 4 Replacing The Supplies; Replacing The Blanket - Ryobi 3302H Operation Manual

L
Replacing the Supplies
1. Replacing the Blanket
After the blanket is used for a long time, the rubber will age causing the adhesiveness to be increased and the surface of
the blanket to become slick and shiny. As a result, paper dust may adhere on the blanket surface, causing such picking
trouble as peeling and roughness on the paper to occur. If this problem becomes worse, paper may be jammed on the
blanket cylinder or ink may not be transferred smoothly onto the blanket resulting in poor printing.
(Note) The blanket jam detector may actuate incorrectly depending on the blanket color. For more detailed information,
please ask your service technician.

«NOTICE»
1. Before mounting the blanket, remove stains, etching solution, and
water on the blanket cylinder surface. Make sure that the cylinder is
completely dry, and then apply rust preventive oil over the entire
surface of the blanket cylinder to protect it.
2. Be careful that the blanket recovery solution and other chemicals
do not adhere on the blanket cylinder surface. If they adhere on the
blanket cylinder surface, wipe them off with a cotton rag containing
water and cleaning solution immediately and apply rust preventive
oil over the entire surface of the blanket cylinder to protect it.
(Recommended rust preventive oil list • Maintenance Edition - 7)
3. Mount the aluminum bars (both the leading and tail edges) in the
blanket cylinder clamp holders exactly. If it is not mounted properly,
when running the press, the aluminum bars may release from the
holders and the blanket cylinder will be damaged.
£WARNING
Mount the blanket cylinder gap safety cover, after mounting the
blanket. Failure to follow this instruction may result in a serious
injury.
