Additional Memory (HL-1050 Only)
The HL-820/1020/1040 printers have 2 Mbytes of standard memory and additional memory
cannot be fitted.
The HL-1050 printer has 4 Mbytes of standard memory and a slot for optional additional
memory. The memory can be expanded up to 36 Mbytes total by installing a commercially
available single in-line memory module (SIMM).
✒
Note
The HL-820/1020/1040 machine memory cannot be expanded.
Additional memory is useful and may be necessary if you are using the Page Protection
function.

This printer can accept memory SIMMS with the following specifications:
Speed 60 nsec - 80 nsec
Pin Type 72 pin
Height 35.00 mm (1.38”) or less
Output 32 bit or 36 bit

Note
The HL-1050 can also support DIB graphics with a resolution of 1200 x 600 dpi under
Windows 95/98/Windows 3.1 with the supplied printer driver. We recommend to expand the
printer memory to avoid any memory full errors.
The printer has only one slot for a SIMM upgrade. If you want to increase your printer
memory again after you have already installed a SIMM module into the slot, you will need
to remove the previously installed SIMM first. For example if you had previously
increased the printer memory from the standard 4MB to 12MB by adding an 8MB SIMM
and you wish to increase your total memory to 20 MB, you need to remove the installed
8MB SIMM and install a new 16MB SIMM into the printer.
