Blank Pages After Printer Firmware Update
Short answer
B Roll back the network printer's firmware to the previous version, since only the recently updated printer produces blank pages while the older printer works fine.
Question
Which of the following should a technician do to resolve the printing issue?
Key Takeaways
The question tests whether you isolate the fault to the one variable that changed (the recent update) rather than performing generic fixes; the trap is picking a diagnostic step like USB testing instead of an actual resolution.
A network printer that suddenly outputs blank pages only on the recently updated device points to corrupted or buggy firmware, not a client-side driver or cable problem. The correct remediation is to roll the printer's firmware back to a previous, known-good version.
Common mistake: The most common wrong choice is C (test a direct USB connection). That only isolates whether the network path is involved—it is a troubleshooting test, not a fix, and blank output on a recently updated printer will persist over USB because the fault lives in the firmware.
Expert Analysis
Why the Answer Is Correct
Option B is correct because the symptom is isolated to a single device that changed: the printer "was recently updated" while the older printer on the same network, printing the same documents from the same users, works fine. That rules out the driver, the print job, and the network path, leaving the firmware as the only altered component. Rolling back the firmware to the prior version restores the known-good code that previously produced correct output, which is the standard remedy when a vendor update introduces a print-quality regression. Firmware rollback is performed from the printer's embedded web server or embedded admin menu using a previously downloaded firmware image.
Why the Other Options Are Wrong
Option A, restarting the printer to clear memory cache, addresses a transient spool or memory error, but the fault here is persistent and began specifically after an update, so a reboot will not correct defective firmware logic. Option C, testing via USB, is a valid isolation technique but produces no resolution—the blank pages originate in the firmware's raster/processing path and would appear over USB as well. Option D, reinstalling the driver on each computer, is disproven by the scenario: the same users printing the same documents succeed on the older printer, so the client drivers are functioning correctly.
Community Comment Notes
The community voting pattern aligns with this analysis; as the top-voted comment put it, "Roll back the printer firmware" because the "printer worked differently after a recent update while the older printer works fine." That reasoning matches the exam's intent of keying remediation to the single changed variable.
Exam Strategy
When two devices behave differently under identical conditions, treat the differing condition (here, the recent update) as the root cause and choose the answer that reverses that change. Avoid selecting isolation or diagnostic steps like USB testing when a genuine fix is offered.
