LaserJet 2420 & 2430 – can lose Speed, Duplex and Embedded JetDirectĭisabling Embedded JetDirect: Power on printer.
Part numbers are:įormatter PCA (networked with embedded JetDirect) Q3652-69004įormatter PCA (non-networked base model) Q3653-69004ĭisabling Embedded JetDirect: same as for the LJ2420/2430. Firmware for these products is onboard the Formatter. Never change the Formatter and DC Controller at the same time, otherwise the printer will adopt the identity of the slowest product (i.e. LaserJet 4250 & 4350 – can lose Speed and Embedded JetDirect
#Lj 4250 initialize drive serial number#
In these cases a special pjl file with specific serial number information will need to be obtained from division, so that it can be sent to the printer in question to restore it to its original status. If a downgrade does occur then the call will need to be escalated to hp Hardcopy Support.
#Lj 4250 initialize drive upgrade#
In these cases a PJL upgrade will be required. In some cases the Embedded JetDirect can “disappear” if the JDI installed bit is not set. These boards should also NOT be returned to stock once they have been in a printer, since they will no longer be neutralised stock items but have a model assigned to them.įor most of the models below there are two Formatters, a networked version with embedded JetDirect and a standard version without JetDirect. Change only one board at a time, and in each case wait 5 minutes for NVRAM information to be transferred across.Ĭhanging the Formatter and the “backup board” at the same time can result in the printer downgrading to the slowest model in that family. The model number in these cases is backed up by either the DC Controller/ECU Board or a Firmware Dimm, depending on the product. The latest range of LaserJets typically have one Formatter which covers all the models in that family. The part numbers listed have probably been updated. Hey, I stumbled across this while I was in between banging my head against a wall swapping out mucho formatters in a 4350tn.
