Error Group Lights CARTRIDGES Explanation and Action Either: one of the color or black print cartridges is faulty, misplaced or missing. Reseat or replace the cartridge. 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 DATA 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. MEDIA 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. 3-4 HP DesignJet 430, 450C and 455CA Printers User Messages
