USER’S GUIDE

MEMORY BOARD

Additional memory is useful and maybe necessary if you printing a very complex document. Since Brother Printing Solution for Windows relies on effective data compression to ‘squeeze’ a large print job into a smaller space, there are times when data compression cannot squeeze a complex 600 dpi document into a smaller space and a resulting “Print Overrun” error message may occur. When this occurs, you may choose to purchase additional memory, or make changes to your printer driver settings (such as reduce print resolution from 600 to 300 dpi, or change Half Tone setting to Line Art or Photo Graphics).

The HL-720 series printer has 0.5 MB of memory as standard. The memory capacity can be expanded up to 2 MB with an optional memory board. Only one size of memory board is available as an option, giving 1.5 MB memory expansion.

The HL-730 series printer has 0.5 MB of memory as standard. The memory capacity can be expanded up to 2 MB with an optional memory board. Two sizes of memory boards are optionally available: 1 MB memory expansion (giving you a total of 1.5 MB) or 1.5 MB memory expansion (giving you a total of 2 MB). Only one memory board can be installed, so select your board carefully according to your printing needs.
