215 Inking Roller Gear Issue

215 Form Roller Gears I have had some inking issues today. Some passes were ok, while in other passes, inking of the type on the form was uneven. I noticed that the back ink roller, the one that hits the drum, was having trouble with its gear/clutch not aligning properly on most passes (see photo). The front roller gears aligned just fine. I tried several fixes, including taking the collar off and putting it back, making sure that the allen screws were in the right place and the collar at the correct position. This did not fix the problem. I even switched the rollers and the problem still occurs with the back roller. Finally, I removed the washer that had been attached to the brass plate to keep the gear and clutch from clattering. The washer on the forward roller had fallen off, so this was the only difference I could see between the front and back rollers that might cause the back one to not catch properly. Didn’t help. Any thoughts appreciated. Thanks.

Looks like the familiar story with this mechanism: worn clutch pins (MR-110). Because the front gear and clutch is engaged, and the rear is not this indicates that the pin and roller core barrel is gummed up.Clean and lubricate with graphite powder. It does appear that there’s minor wear on the “paddle” or clutch plate. On sheet 106 of the manual it’s called the Form Roller Clutch Trip (MB-104).

Hi Katie, if the problem you are describing is the roller not re-engaging the clutch after getting a fresh charge of ink. Check the brass lever (paddle) on the far side frame that pushes against the rollers to disengage the clutches, make sure there is clearance when the paddle is in the retracted position. There is a set screw and locking nut behind the paddle for adjustment. I’ll be working on a #4 all day today and can be reached @ 859-250-2082 for more troubleshooting ideas.
Warm Regards

Hello Katie,
Is the clutch spring still intact? I can’t tell from the photo.
