Description: Hewlett-Packard LaserJet 4650 color laser printer SNMP MIB providing color consumable and print engine status monitoring.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is LJ4650-MIB?

LJ4650-MIB is a Hewlett-Packard Company enterprise MIB built on HP's PML (Printer Management Language) object tree (device/device-system, processing-subsystem, destination-subsystem/print-engine) for managing an HP LaserJet 4650-class color laser printer. It exposes device-level status and diagnostics such as self-test control, error logging with timestamped error codes and cumulative engine page counts (error1-time-stamp/error1-code through multiple error slots), control-panel display contents and button/key press events, energy-star/sleep-mode timers, and installed memory SIMM type/capacity across multiple slots and banks. Under the print-engine subtree it models input trays, output bins, marking agent/consumables (consumables, consumables-status, consumables-life), and print-media handling, giving a monitoring system visibility into consumable life and engine health alongside classic device-management actions like cancel-job, form-feed, and os-execute-file. Because most objects are HP-proprietary PML leaves rather than standardized Printer-MIB (RFC 3805) objects, it is typically polled alongside the standard Printer MIB rather than in place of it. It is deployed on HP LaserJet 4650-family color laser printers, and administrators can download the LJ4650-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LJ4650-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • HP LaserJet 4650-series color laser printers

Monitoring Examples

An operator polls the consumables-status/consumables-life subtree to check remaining toner/drum life alongside the print-engine's error-log objects (error1-code, error2-code, ...); a low consumable-life reading combined with a recently logged error code and engine page count would indicate an imminent consumable replacement or an engine fault requiring service.

What Can Be Monitored

  • consumable (toner/drum) life and status
  • print-engine error log entries and page counts
  • installed SIMM memory type/capacity per slot
  • control-panel display and button/key press events
  • sleep-mode/energy-star timer settings
