    NAME

    escputil - maintain Epson Stylus inkjet printers
     
    

    SYNOPSIS

    escputil [ -P printer | -r device ] [ -m model ] [ -u ] [ -c | -n | -a | -i | -d | -o | -s | -l | -M | -h ] [ -q ]  

    DESCRIPTION

    escputil is a command line utility to perform various maintenance tasks on Epson Stylus inkjet printers. These tasks include head alignment, head cleaning, nozzle check, printer identification, and retrieval of ink level from the printer.  

    OPTIONS

    escputil accepts the following options:
    -P, --printer-name=printer
    Specify the name of the printer to operate on. The default is the default system printer.
    -r, --raw-device=device
    Specify the name of the device to write to directly rather than going through a printer queue. You must use this (rather than specifying a printer) when retrieving ink levels or identifying the printer, or if you wish to perform head alignment without specifying the printer model.
    -m, --model=model
    Specify the precise printer model for head alignment.
    -u, --new
    The printer is a new printer (Stylus Color 740 or newer).
    -c, --clean-head
    Clean the print head. This can also be performed from the printer front panel.
    -n, --nozzle-check
    Print a nozzle test pattern. Dirty or clogged nozzles will show as gaps in the pattern. If you see any gaps, you should run a head cleaning pass or two.
    -a, --align-head
    Align the print head. CAUTION: Misuse of this option may result in poor print quality and/or damage to the printer. You must either specify the printer model with the -m option, or use the raw printer device to allow escputil to detect the printer model.
    -i, --ink-level
    Obtain the ink level from the printer. This requires read/write access to the raw printer device.
    -d, --identify
    Query the printer for make and model information. This requires read/write access to the raw printer device.
    -o, --align-color
    Align the color print head (used by Stylus Color 480 and 580 only). CAUTION: Misuse of this option may result in poor print quality and/or damage to the printer.
    -s, --status
    Retrieve printer status.
    -l, --license
    Display the license/warranty terms of this program.
    -M, --list-models
    List the supported printer models.
    -h, --help
    Display a list of all command line options.
    -q, --quiet
    Suppress the banner.
     

    BUGS

    USB-connected printers sometimes fail to identify or return ink levels. You may have to repeat the command. This is probably a timing issue in escputil, not a flaw in the printer.

    Anything requiring bidirectional communication with the printer (identify, ink levels, or head alignment without specifying the printer model) requires read/write access to the printer port (for example /dev/lp0). This may require these operations to be performed as root. In addition, kernel support is required for bidirectional communication. For Linux version 2.2, CONFIG_PRINTER_READBACK should be enabled; this is called CONFIG_PARPORT_1284 on 2.4 and later kernels.

    If the printer is performing self-test or head cleaning on power up, the identify and ink level commands will time out, although the printer successfully receives the command. The command will need to be reissued when the printer is quiescent.
