Identification
Model and Serial Numbers
The model and serial numbers are listed on identification labels located on the rear of the printer. The model number is alphanumeric, such as C4085A for the HP LaserJet 8000 printer and C4228A for the HP Mopier 240. The serial number contains information about the Country of Origin, the Revision Level, the Production Code, and production number of the printer. The rear labels also contain power rating and regulatory information as shown in figure 1-1.

Figure 1-1

Sample Model and Serial Number Label for the Printer The identification labels for the 2000-sheet Input Tray and 2 x 500sheet Input Tray are located on the back panel, directly below the identification labels on the printer. To locate the identification labels for the 8-bin Mailbox and 5-bin Mailbox with Stapler, detach the device from the printer. The identification labels are located on the bottom right of the front side (side that attaches to printer). To locate the identification labels for the 7-bin Tabletop Mailbox, detach the device from the printer. The identification label is located on the bottom side of the back cover.
