Printer Assembly
Removal
To remove the printer assembly, first open the printer cover to gain access to the
printer assembly. Remove the pump cartridge to allow enough free space for
removing the printer assembly without interference in the printer compartment.
The pump cartridge can be removed by grasping it and pulling it up. Next
remove the printer paper and set aside. Two thumb screws which hold the printer
assembly in place can now be loosened. After the thumb screws have been
loosened, the printer can be slid towards the rear of the analyzer. Disconnect the
printer ribbon cable that attaches to the printer. The printer assembly can now be
removed.
