Open the print-cartridge door and remove the print cartridge. 2. Use needle-nose pliers to release the transfer roller tabs at the end of the roller, near the right side of the printer. CAUTION Do not break the tabs, and do not touch the rollers. Figure 6-43 Removing the transfer roller 3. Lift up the end of the roller near the right side of the printer, and then slide it toward the right side of the printer while pulling it out of the printer. 128 Chapter 6 Removal and replacement ENWW
