Maintenance

Replacement parts

Name	Part no.	Stock	Unit
Stripper pad	`019-11833`	3 / riso	Paper feed
Stripper pad	The stripper pad puts upward force and friction on the multiple pages that are fed into the pickup roller, so that the teeth of the tire only propel the top sheet into the riso. It is the rubber part that wears the fastest and must be replaced regularly for stable paper feed. Very old risos may use a different stripper unit, which takes an older stripper pad type (a thin square), otherwise this part is universal. An alternative grey stripper pad is listed under part no. `019-11834`—it uses a harder material, which is meant to last longer and be better for heavier paper stocks.
Feed roller (solid)	`003-26306`	1 / riso	Paper feed
Feed roller (solid)	The RP uses a solid core roller for the center of its 3 feed rollers (the other two use standard feed tires). The standard core + tire can be used, but an appropriate spacer must be made to keep the roller properly centered on its shaft.
Exit belts (RP)	`629-94570` `629-93280`	1 set	Paper ejection
Exit belts (RP)	Exit belts transport paper out of the riso—a suction fan pulls air down through holes in the belts to hold the paper to them while the main motor powers the belts. The RP uses 4 belts, 2 wide ones with holes, and 2 narrower solid ones—a full set is 2 of each. As they wear, they will stretch out and slip on their rollers—paper will become stuck in the exit area (particularly larger sheets of heavier stocks). Belts can be tested by dragging them with a fingertip—each pair of belts should move together—if individual belts slip, it's a sign that all should be replaced.
Separator collar (RP)	`030-15113`	1 / riso	Paper ejection
Separator collar (RP)	A small, wide roller that sits on a bracket at the back of the bar supporting the separator needle. When it breaks down, the separator needle will catch more frequently on the drum, resulting in stock drums and lost timing. This part is past the point of replacement on all RP machines—if it has not yet been replaced in the life of the machine, it should be. This is the most common cause of drums stuck in these machines, which can also result in permanent damage to the back flange of the drums.
