Replace All 4200 4250 4300 4350 and 4345 Pickup Separation Rollers RM1-0036 and RM1-0037
The older HP LaserJet printers incorporate four “D” pickup rollers mounted on a black plastic shaft that pick up paper and move it toward two feed/separation rollers.
When they rollers wear out, these printers can experience multi-feed and paper jam issues. The solution is simple—replace all the rollers.
Some technicians, however, only replace the feed/separation rollers and neglect the “D” rollers, which are likely worn as well. This may solve the problem temporarily, but it can also cause another service call when the “D” rollers get worn enough to cause more issues.
The same is true for two newer HP monochrome laser printers: the LaserJet 4200 4250 4300 4350 and 4345. In these printers, there are two feed/separation rollers (RM1-0037), just as in the 4000/4050/4100.
The 4200 4250 4300 4350 and 4345, however, do not use four “D” rollers for pickup. Instead, they have a pickup system and round pickup roller (RM1-0036) that feeds paper toward the two feed/separation rollers.
If you work on the 4200 4250 4300 4350 and 4345 printer, remember these two important tips:
When multi-feed or paper jam problems related to pickup occur, make sure to change all three rollers—the pickup and the two feed/separation.
Remember that the 4200 and 4300 have a pickup roller that is different from the 4000/4050/4100. Having the right rollers for each printer will save a return visit to your customer’s site.
