    Your software (operating environment, applications and printer 
    drivers) controls the printing process. Make sure you have 
    selected the right driver for use with your printer. See your 
    software documentation for more information.

    garbled.Incorrect driver is 
    installed.Install an appropriate driver.
    Printer’s output 
    is below rated 
    speed.Much of the 
    printing delays will 
    be caused by your 
    Sometimes purely 
    text documents will 
    print slowly 
    depending on the 
    selected fonts and 
    how they are 
    transferred to the 
    printer.For maximum speed, use text in 
    your document and use a printer 
    resident font.

    printer’s default is 64. Adjust 
    software accordingly, or set LINES

    The following options are available to extend the performance of 
    your printer:
    >10/100 BASE-TX Network Interface Card: to make the 
    B4400 and B4600 network compatible
    >16, 32, 64, 128, 256MB RAM DIMM: to extend the main 
    memory of your printer and speed up the processing of 
    large files
    >RS232C Card: to provide serial interface capability for the 
    B4400 and B4600
    >Second paper tray: to increase your printer’s paper 
    handling capacity by 500 sheets (80g/m²)
    >Multi Purpose Tray: to extend the range of media your 
    printer can accommodate (capacity 100 sheets (80g/m²) 
    or 50 envelopes)
    >One of the following can be added:
    (a) 8MB Flash DIMM: to allow the storage of additional 
    fonts or bar codes for the B4400, B4400n, B4600, 
    (b) 16MB Flash DIMM: to allow the storage of additional 
    fonts or bar codes for the B4400, B4400n, B4600, 
    (c) PostScript PS level 3 DIMM: to add PostScript 
    emulation to the B4600 or B4600n. Cannot be added 
    in conjunction with extra flash memory. 
    (d) The B4600 PS option is supplied as 2 DIMMs: a PS 
    DIMM and a 16MB RAM DIMM. When fitted into a 
    basic B4600 or B4600n (i.e. one with no memory 
    upgrade already fitted) the PS DIMM will expand into 
    the 16MB RAM DIMM in order to work, and the 
    amount of memory available for general operation of 
    the printer will therefore not change. It will remain 
    at 16MB, which is the printers base memory.
    (e) If you require to install a PS upgrade into a B4600 or 
    B4600n which already has a memory upgrade 
    installed, discard the 16MB RAM DIMM which ships

    with the PS option and install only the PS DIMM. The 
    result will be that the amount of overall memory 
    available to the printer will decrease by 16MB as the 
    PS code expands into 16MB of RAM currently 
    installed. For example, a user who already has 
    128MB installed (total memory is therefore 
    128+16=144MB) will fit only the PS DIMM and will 
    then have 128MB of RAM left for printing.
    To install any of the above options, follow the detailed installation 
    sheet that accompanies the option.
