PJL Data stream upgrade through a parallel port The DOS parallel port upgrade can only be used for upgrading copy capability. If digital sending is being used on the MFP, refer to the digital sender configuration utility upgrade method. 1 Download and unzip the self-extracting CMFxxx.EXE files from www.hp.com and copy it to the PC that will be directly connected to the MFP to perform the upgrade. 2 After expanding, locate the CMFxxx.PJL file and CMFDIR.PJL if needed. Default directory is C:\TEMP 3 Directly connect the PC to the MFP you want to upgrade, usually with a parallel cable. 4 Turn the MFP on and wait until the control panel displays READY .
5 If the PC is Windows based, you may have to modify the port settings so that MS DOS print jobs are not spooled. This is done in Windows 95/98 by selecting Start, Settings, Printers, choose the printer using LPT1, select File, Properties, Details, and Port Settings. 6 Open a DOS window. 7 Change directories to the directory containing the CMFxxx.PJL file, if necessary. 8 If the copy module firmware directories are available, go to step 9. If you cannot find the copy module firmware directories, type copy/b CMFDIRS.PJL lpt1 and press the enter key. Note This step may result in a disk error if the directories are on the MFP hard disk.
This temporary error does not indicate a problem with the disk and will be cleared with a power cycle. The error can be cleared by pressing the “Go” key. 9 Type copy/b CMFxxx.PJL lpt1 and press the enter key. 10 The MFP control panel should display PROCESSING for about 30 seconds, then return to displaying READY without printing a page. 11 Turn the MFP and the Copy Module off and then back on to complete the upgrade.
