Paper Creasing During 2-Sided Printing
One persistent issue faced by users of the HP LaserJet M601dn is paper creasing, particularly when utilizing the two-sided printing function. This problem can manifest as creases on either the right or left side of the page. Such creasing not only detracts from the overall appearance of printed documents but can also lead to paper jams or misfeeds during the printing process. Users encountering this issue are often advised to check the printer settings, ensuring the correct media type is selected and confirming that the paper is loaded properly. Additionally, verifying that the printer rollers are clean and in good condition can help minimize creasing. Source
Blank or Stained Pages
Another significant frustration arises when the printer completes its cycle, yet the pages output are either blank or only lightly stained. This problem can occur due to a few underlying factors, including toner issues or complications with the printer’s imaging components. When the printer goes through the stages of pulling paper, applying toner, and fusing it, but delivers an unsatisfactory out result, users should first examine the toner cartridges for sufficient toner levels and installability. If the cartridges are functioning properly, it may necessitate an in-depth look into the printer’s imaging drum or the fuser assembly, both of which play critical roles in ensuring proper printing.

Error Code 59.00.90 and Its Implications
The HP LaserJet M601dn is also prone to displaying error code 59.00.90, which can disrupt the workflow significantly. This error typically results from a malfunction in the registration bearing, often becoming obstructed with ink, thus preventing the shaft from turning. When the motor stops functioning due to this blockage, it hinders the printing process entirely. Users experiencing this error are encouraged to clean the registration bearing and check for any ink residue that might obstruct normal operation. Consistent maintenance in this area can prevent frequent occurrences of this error and ensure more seamless printing operations. Source
Poor Fusing and Print Quality Issues
Users have reported concerns about poor print quality, characterized by smeared toner, ghosting effects, and toner rubbing off. These issues may largely stem from an outdated or incorrect firmware version that defaults the print mode for plain paper to “Light” rather than the appropriate “Normal” setting. This setting leads to insufficient heat during the fusing process, causing the toner not to adhere properly to the paper. Regular firmware updates are essential for optimizing printer performance and preventing such quality issues. Proper maintenance of the fuser assembly can also alleviate these problems. Those experiencing ongoing issues with print quality should consider updating their firmware and ensuring their printer settings match the type of paper being used. Source Source
Challenges with High Capacity Toner Cartridges
Finally, another common inconvenience for users of the HP LaserJet M601dn is its incompatibility with high-capacity toner cartridges. This limitation requires users to frequently replace toner, increasing operational costs and potentially leading to interruptions in printing workflows. For businesses that rely heavily on printing, this can be a frustrating setback. Users should be aware of the printer’s limitations and plan for regular toner purchases to avoid running out during critical printing jobs. Awareness of the specific cartridges suitable for the M601dn model ensures users maintain optimal printing capabilities without unexpected downtime. Source
