Check to make sure the coprocessor board is securely heldby the locking tabs.• If the board tilts easily back to the 30° angle, repeatsteps 1 to 4.• If the board does not move, installation is complete.For installation of SIMMS, see A5.Install additional optionsIf you purchased additional options for your printer, you caninstall them at this time while the system controller board is outof the printer. If there are no additional options to be installed,continue with step 6.System controller board reinstallation6. Place the system controller board into the receiving rails ofthe printer.7. For reinstallation of the system controller board, reverse theremoval process in steps 1 to 6 of the PDL installationprocedure.8. Print a configuration sheet. If the sheet prints and indicatesthe PDL PWB and coprocessor are present, installation wassuccessful.Caution: Cable connectors may interfere with thereinstallation of the system controller board; therefore, routethem carefully.XEROX 4213 LASER PRINTER USER GUIDE A4-11
