7 LaserJet 5 Error Map The LaserJet 5/5M/5N printer has error messages that are similar to the LaserJet 4/4M/4+/4M+. Use the following table to look up the LJ5 error and take the recommended action. If the recommendation is to see another error, for example See 00 POWERSAVE, look up the recommendation for that error in the Printer Message Troubleshooting section (Tables 7-1 and 7-2). Note The LaserJet 5 printer's Go key replaces both the Online and Continue keys previously used to resolve some of the temporary errors in the LaserJet 4 and 4 Plus printers. Note For any LaserJet 5 error message preceded with a number from 20 through 81, look up the equivalently-numbered message in Table 7-1 and proceed as directed.
