Understanding Fuser Errors (50.22.xx)
One of the more specific issues users of the HP LaserJet Enterprise 600 M601 series might encounter is a fuser error, typically indicated by codes in the 50.22.xx range, such as 50.22.00 or 50.22.11, displayed on the printer’s control panel. The fuser is a critical component responsible for bonding the toner to the paper using heat and pressure. When these errors appear, they signal a problem with the fuser warming up correctly. This could be due to various internal issues preventing the fuser from reaching the necessary operating temperature. Addressing these errors often requires specific troubleshooting steps, and consulting the printer’s documentation or HP support resources is recommended.

Addressing Paper Handling and Feeding Problems
Paper handling is a common area for printer issues, and the HP LaserJet Enterprise 600 M601m is no exception. Users have reported problems with how the printer pulls paper, such as unexpectedly drawing the first page from Tray 1 (the fold-down tray) but subsequent pages from Tray 2 (the 500-sheet tray), even when sufficient paper is available in Tray 1 for the entire job. Another reported issue is Tray 2 lift errors, where the tray mechanism doesn’t lift correctly, or the motors don’t spin up. This specific problem might stem from a physical obstruction or potentially a damaged or dislodged cartridge contact within the printer’s body. Incorrect paper feeding, in general, is a broad category that requires careful investigation, often starting with checking the paper type and loading.

Essential Troubleshooting Steps and Resources
When troubleshooting problems with your HP LaserJet Enterprise 600 M601m, a systematic approach is key. A common recommendation is to follow a solve problems checklist. Basic initial steps should include ensuring the printer is ready for operation and verifying that the correct paper type is loaded in the trays. It’s also crucial to ensure the printer has the most recent firmware installed, which can often resolve known bugs and improve performance. A helpful diagnostic step is to print a test page. If the test page for printing comes out correctly, it suggests that the printer hardware itself is functioning properly. In this case, the root cause of the issue is likely related to the computer sending the print job, the printer driver installed on the computer, or the specific program you are printing from. HP offers extensive online support, including detailed troubleshooting guides, manuals, and the latest software and drivers for the HP LaserJet Enterprise 600 M601 series, providing valuable resources for obtaining a printable test page and following steps to print test page outputs.

Accessory Requirements for Expanded Paper Capacity
For users who require significant paper capacity with their HP LaserJet Enterprise 600 M601 printer, adding multiple input trays is a common solution. However, when configuring the printer with more than three HP LaserJet 500-sheet Input Tray Feeders (CE998A), or with one HP LaserJet 1500-sheet Input Tray (CE398A) in addition to more than one other tray, an important requirement for product stability comes into play. To ensure the printer remains stable and functions correctly with this expanded setup, purchasing a specific HP LaserJet P4010/P4510/600 Series Printer Stand (CF063A/CB525A) is mandatory. These stands are considered paper handling accessories and are available for purchase separately. Failing to use the required stand with such configurations could potentially lead to operational issues or instability.
