HP LaserJet MFP M234sdw Driver, Wi-Fi Setup, Scanner Not Working, Last Page Missing, ADF Not Scanning, Black Copies, Offline Printing, HP Connected, Error Code 11, and Cartridge Error Problems

The HP LaserJet MFP M234sdw is a wireless monochrome multifunction printer, so reported driver problems usually involve Wi-Fi setup, HP Smart connection state, scanner communication, ADF behavior, firmware timing, error code 11, cartridge state, and printer offline behavior. The existing cases on this page showed that the device can appear partly functional while another function fails, so printing, scanning, ADF feed, firmware, cloud connection, and cartridge state need to be treated separately.

HP M234sdw will not connect to Wi-Fi despite strong signal

Users reported that the printer showed a strong wireless signal but could not complete Wi-Fi setup. Rebooting the printer, router, and devices did not change the outcome.

The useful outcome from these reports was that signal strength alone did not prove the M234sdw had completed network setup. The next practical focus was resetting Wi-Fi setup mode through the printer’s control-panel button sequence and rebuilding the connection from a clean wireless state.

Scanner misses the last page

Users reported that scans consistently missed the final page of a document even though earlier pages were processed normally. The behavior looked like a scan workflow or document-handling problem rather than a total scanner failure.

The useful takeaway was to separate last-page loss from full scanner communication failure. Driver and software updates were the reported repair path, but the reports did not prove that the missing-final-page behavior was caused by the normal print driver alone.

Scanner reports “Couldn’t Connect to Scanner”

Users reported that scanning suddenly stopped and the printer showed a “Couldn’t Connect to Scanner” type failure even though the device had connected successfully in the past. Printing was not clearly broken at the same time.

The reports narrowed the issue to the scanner communication path. Driver checks, diagnostic tools, and Windows scanning service checks were attempted, but the scanner connection failure did not have a confirmed single repair outcome. This belongs with Scanner Cannot Communicate With Computer.

Automatic document feeder will not scan

Users reported that the document feeder failed to scan pages while the flatbed scanner, copying, and printing continued to work normally. That separated the failure from a complete scanner or printer breakdown.

The useful outcome was that the ADF needed to be treated as its own path. Cleaning feeder rollers, checking firmware, and trying single-page tests were the reported attempts, while flatbed scanning and printing still working showed that the whole scanner was not necessarily offline.

Scanner calibration is followed by solid black copies

Users reported that during copying, the printer initiated a calibration cycle. Afterward, all copies printed completely black and the scanner light no longer turned on.

In the reported outcome, a hard power reset and firmware update were performed, and normal scanning and copying resumed. The reason calibration caused the failure was not explained, but the case ended with scanner and copy functions working again after reset and firmware work.

Printer scans but will not print and appears offline

Users reported that the HP M234sdw could scan successfully and showed a Wi-Fi connection, but HP Smart showed it as offline. Neither Windows nor an iPad could print to it.

The useful outcome was that scanning and Wi-Fi status did not guarantee a working print route. Multiple HP-recommended repair steps were attempted, including disabling Smart Install, but the reported case kept printing separate from scanner success and treated the print path as the failing side.

Printer is on the local network but not connected to HP Connected

Users reported that the printer was reachable on the local network and visible in HP apps, but still claimed it was not connected to HP Connected services. This separated local network visibility from cloud/service connection state.

Diagnostic tools and restarts were used. The useful takeaway was that local reachability and HP Connected status were not the same condition. A printer could appear on the local network while still failing the HP Connected service state.

Error code 11 appears after firmware change

Users reported that the printer abruptly stopped working and displayed HP M234sdw error code 11. Cartridge reseating, cleaning, reboots, and firmware reinstall attempts initially failed. The issue appeared suddenly and was tied to firmware timing in the reports.

In the reported outcome, older and current firmware packages were attempted multiple times. Applying the March 11, 2025 firmware update through HP Smart eventually succeeded and restored printing, even though earlier attempts with the same firmware had failed.

Second-hand M234sdw stays in orange error state

Users reported that a newly acquired second-hand M234sdw showed an orange error light and refused to print even after factory resets, firmware updates, and repeated cartridge reseating.

In the reported outcome, replacing the toner cartridge resolved the error completely. Until the cartridge was changed, the printer remained locked in the error state. This preserved case shows that device-side cartridge condition could block operation after resets and firmware checks did not help.
