APPENDIX 20. PAPER CASSETTE INFORMATION (FOR EUROPE ONLY)
The paper cassette fitted to the printer is different from the service manual information for
printers shipped to Europe as follows:-
(1) The paper cassette supplied with the HL-
1850/1870N printer has a plastic rib on
the paper tray cover.
(2) The plastic rib is removed from the tray
cover for the paper cassette supplied with
the LT-500, (optional Lower Tray Unit) as
shown on the right;
Fig. A- 14
(3) If the optional LT-500 Lower Tray Unit is installed onto the HL-1850/1870N printer, it is
necessary to exchange the cassette supplied with the LT-500 Unit with the upper cassette
already fitted into the printer. Install the cassette originally fitted in the printer into the LT-
500 Unit.
Failure to do so will cause paper jams as the paper cannot be fed from the lower cassette
to the printer body because the plastic rib on the paper tray cover is blocking the paper
path.
(4) For paper cassettes supplied as spare parts, the plastic rib has been cut off so that you
can use it as both an upper cassette and lower cassette.
