General Definition of Safety Symbols
International caution symbol (refer to manual): the product is marked with this symbol when it is necessary for the user to refer to the instruction manual in order to protect against damage to the instrument.
Indicates dangerous voltage (terminals fed from the interior by voltage exceeding 1000 volts must also be marked).
Protective conductor terminal. For protection against electrical shock in case of a fault. Used with field wiring terminals to indicate the terminal that must be connected to ground before operating equipment.
Low-noise or noiseless, clean ground (earth) terminal. Used for a signal common, as well as providing protection against electrical shock in case of a fault. A terminal marked with this symbol must be connected to ground in the manner described in the installation (operating) manual, and before operating the equipment.
Frame or chassis terminal. A connection to the frame (chassis) of the equipment, which normally includes all exposed metal.

This light is ON and STEADY.
This light is ON and FLASHING.
This light is OFF or this is the relevant light.
The state of this light is not relevant.
Lights Explanation and Action

Key to table starting below
1: Status group
2: Error group
Lights Explanation and Action
The printer is not ready to print.
Check the state of the other lights and look them up in this table.
The printer is ready to print.
Send your print from your computer or, for a special internal print, press the appropriate key combination.
The printer is busy with a task or is receiving a file. Wait. If combined with one of the four media type group lights flashing. The printer is waiting for the media to dry. This can be terminated by pressing Form Feed .
You are loading media and need to realign it, even if it seems perfectly aligned.
Lower the media lever, realign the media, and raise the media lever.
The printer is ready, but you need to load media.
When you are ready to print, load media.
The printer has a file in memory, which it is waiting to print, but no media is loaded.
Load media.
Lights Explanation and Action
Either: one of the color or black print cartridges is faulty, misplaced or missing.
Or: you have loaded a print cartridge of the wrong type for this printer. For the correct part numbers of the cartridges supported by this printer, see Chapter 7.
Either: the current print is too large for the printer’s memory. Look on your computer screen for any error message: some drivers, for example the Microsoft Windows driver supplied with your printer, allow you to choose a different printing mode and try to send the file again. In the case of the Microsoft Windows 95 driver shipped with the printer, the relevant field is called “Process document” in the Options dialog box.
Otherwise, you may need to install more memory to print this print. For information on available memory expansion modules, see Chapter 7.
Or: there is a problem with the serial interface. The printer’s settings for baud rate and parity must be the same as those of the computer sending the data.
Either: the sheet you loaded is misaligned. Realign it again. See the Users Guide for a short tutorial on loading media.
Or: it is an invalid size. For supported media sizes, refer to the Users Guide.
Or: the media lever is lowered. Raise the lever.
Or: the cover is open when the printer is initializing. Lower the cover.

General Definition of Safety Symbols
International caution symbol (refer to manual): the product is marked with this symbol when it is necessary for the user to refer to the instruction manual in order to protect against damage to the instrument.
Indicates dangerous voltage (terminals fed from the interior by voltage exceeding 1000 volts must also be marked).
Protective conductor terminal. For protection against electrical shock in case of a fault. Used with field wiring terminals to indicate the terminal that must be connected to ground before operating equipment.
Low-noise or noiseless, clean ground (earth) terminal. Used for a signal common, as well as providing protection against electrical shock in case of a fault. A terminal marked with this symbol must be connected to ground in the manner described in the installation (operating) manual, and before operating the equipment.
Frame or chassis terminal. A connection to the frame (chassis) of the equipment, which normally includes all exposed metal.

The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not correctly performed or adhered to, could result in personal injury.
Take care not to cut yourself on the encoder strip inside the plotter.

Lights Explanation and Action
The printer is not ready to print.
Check the state of the other lights and look them up in this table.
The printer is ready to print.
Send your print from your computer or, for a special internal print, press the appropriate key combination.
The printer is busy with a task or is receiving a file. Wait. If combined with one of the four media type group lights flashing. The printer is waiting for the media to dry. This can be terminated by pressing Form Feed .
You are loading media and need to realign it, even if it seems perfectly aligned.
Lower the media lever, realign the media, and raise the media lever.
The printer is ready, but you need to load media.
When you are ready to print, load media.
The printer has a file in memory, which it is waiting to print, but no media is loaded.
Load media.
Lights Explanation and Action
Either: one of the color or black print cartridges is faulty, misplaced or missing.
Or: you have loaded a print cartridge of the wrong type for this printer. For the correct part numbers of the cartridges supported by this printer, see Chapter 7.
Either: the current print is too large for the printer’s memory. Look on your computer screen for any error message: some drivers, for example the Microsoft Windows driver supplied with your printer, allow you to choose a different printing mode and try to send the file again. In the case of the Microsoft Windows 95 driver shipped with the printer, the relevant field is called “Process document” in the Options dialog box.
Otherwise, you may need to install more memory to print this print. For information on available memory expansion modules, see Chapter 7.
Or: there is a problem with the serial interface. The printer’s settings for baud rate and parity must be the same as those of the computer sending the data.
Either: the sheet you loaded is misaligned. Realign it again. See the Users Guide for a short tutorial on loading media.
Or: it is an invalid size. For supported media sizes, refer to the Users Guide.
Or: the media lever is lowered. Raise the lever.
Or: the cover is open when the printer is initializing. Lower the cover.
