Certain plotter failures that can occur will prevent the plotter from reaching the “STATUS /Ready for Media” state. If one of these problems occurs, switch the plotter OFF. Press and holddown the ENTER and the UP ARROW buttons while switching the plotter ON. This will allowaccess to the service tests.
# $ # " $!
# # $!
#
" #
If no button is pressed for 1.5 minutes, the front panel will return to the “Status” menu.
In some cases a quick press of a button may not be recognized by the processor. When pressing abutton, be sure to press it deliberately and all the way to the bottom of its travel.
If the plotter hangs up during a test, switch the plotter OFF and restart at step 1 again.
In some cases the plotter may revert to the “STATUS” message upon exiting a test. To return tothe service menu, perform the above steps.

Remove any media already loaded into the plotter before performing the calibration.
Place a sheet of polyester film over the top of the plotter for approximately 10 minutes to let itstabilize to the environmental conditions. Use a sheet approximately 24 x 36 inches (61 x 91 cms).Roll media may also be used. When using polyester film, load it with the matte(dull) side down.

Certain plotter failures that can occur will prevent the plotter from reaching the “STATUS /Ready for Media” state. If one of these problems occurs, switch the plotter OFF. Press and holddown the ENTER and the UP ARROW buttons while switching the plotter ON. This will allowaccess to the service tests.

If no button is pressed for 1.5 minutes, the front panel will return to the “Status” menu.
In some cases a quick press of a button may not be recognized by the processor. When pressing abutton, be sure to press it deliberately and all the way to the bottom of its travel.
If the plotter hangs up during a test, switch the plotter OFF and restart from step 1.
In some cases the plotter may revert to the “STATUS” message upon exiting a test. To return tothe service menu, perform the above steps.

media jam A situation in which media becomesblocked in the plotter mechanisms.
media-jam lever Pinch-arm lever.
media-length calibration Media-sensorcalibration.
media-sensor calibration Media-lengthcalibration.
mil 1/1000 of an inch.
minimum pass time The time necessary for inkto dry sufficiently before the plotter can placemore ink adjacent to it.
MIO Modular Input/Output.
mm Millimeter(s).
monitor mode Service monitor.
MS-DOS MicroSoft Disk-Operating System
no negative motion An RTL command thatindicates to the plotter that it will receive all dataalready in the order in which it should be plotted.
off-axis ink system A system whereby ink ispumped to the cartridges from a reservoir thatdoes not move with the carriage.
PAL Programmable Array Logic.
palette A set of pens for which width and %shading are defined using the setup sheet or thegraphics software.
paper axis Media axis (X-axis).
parity An error-checking method forinformation transfer between a computer and aperipheral device. Parity is used to check theaccuracy of binary data.
pass A movement of the carriage from left toright, or from right to left, as it plots the graphic.
pass advance The distance that the mediaadvances between carriage passes.
PC Personal Computer.
PCA Printed Circuit Assembly.
pen 1. Even though the inkjet plotter has nophysical pens, the lines it draws match theattributes for pens numbered 1 through 8 in theapplication software. (See also “palette.”)2. Sometimes used instead of “print cartridge.”
pinch-arm lever Pinch-wheel lever, media-jamlever.

Product Line 30 Hewlett-Packard’s productline of large-format, pen and thermal-inkjetplotters.
PWM Pulse-Width Modulation.
RAM Random-Access Memory.
raster 1. A matrix of dots, or pixels, whereeach pixel is defined by a bit. A bit that is “on”will print a dot on the paper. A bit that is “off”will leave the area blank.2. A method for defining a plot directly in termsof the pixels rather than as vectors.
raster image processor Software that convertsgraphics data to pixel format.
relative humidity The ratio of the amount ofwater vapor actually present in the air to thegreatest amount possible at the same temperature,(from Webster’s Ninth New Collegiate Dictionary, Merriam-Webster 1991).
resolution A measure of image sharpnessexpressed as a number of lines per unit length.When referring to plotters, addressable resolutionmeans the smallest move the plotter can makeprogrammatically.

Glossary-6 C4705-90000
swath That portion of a drawing plottedbetween advances of the drive roller in
mode. (In mode, the drive roller advanceshalf a swath at a time; in mode, it mayadvance a full swath or half a swath, dependingon whether the plot is color or monochrome.)
TCP/IP Transmission Control Protocol /Internet Protocol.
theta-Z error A print-quality error causedwhen the nozzles on a cartridge are notperpendicular to the carriage axis. The errorshows up as jagged vertical lines.
translucent Describes a type of media throughwhich light passes.
UART Universal Asynchronous ReceiverTransmitter.
unidirectional print mode A print mode inwhich plotting is performed while the carriagemoves in one direction, and no plotting isperformed while the carriage moves in theopposite direction.
vellum A type of strong paper.
VLS Vertical-line straightness.
X-axis Media axis.
X-axis calibration Accuracy calibration.
Y-axis Carriage axis.
