Resolving Samsung Express C1860FW Laser Printer Stuck on Logo Issue: A Comprehensive Tech Overview

User Experience and Initial Attempts

Users have encountered this problem for various reasons, including firmware updates, password issues, and suspicions of intentional deactivation by the manufacturer due to the printer's age and low cartridge levels. Initial attempts to resolve the problem, such as pressing key combinations during restarts, have proven ineffective.

Solution 1: Power Cycling and Samsung Easy Printer Manager

One user successfully resolved the issue by following a specific sequence of steps:

1. Extended Power Off: Switch off the printer using the ON/OFF switch for 3-4 days, leaving all cables connected.
2. Install Samsung Easy Printer Manager: Download and install "Samsung Easy Printer Manager 1.05.82.00" on a connected PC, then restart the computer.
3. Power On During Print Command: Attempt to print a document while turning on the printer. The user reported that the display started working again after following this sequence.

This suggests that an extended power-off period may allow the printer to receive a print command via USB during startup, triggering the display to function correctly.

Solution 2: Power Off for Firmware Update

Another user shared an experience of the display going into blue mode after a failed firmware update. The solution involved:

1. Extended Power Off: Turn off the printer for at least one day.
2. Power Drain: Press the power button while the printer is off to remove residual power from the power supply.
3. Wait for Display Return: Leave the printer off for an additional 2-3 days, waiting for the display to come back.

Once the display is restored, the user recommends immediately updating the firmware to reprogram the keyboard and controller.

Solution 3: Hardware Fix - JC92-025051 PBA-GUI OPE

Another user, "Ope," shared a hardware solution involving the replacement of the JC92-025051 PBA-GUI OPE board located under the touchscreen. The steps included prying the panel off, disconnecting four screws and a few connectors, including a hidden one on the bottom side of the board. The user suggests this board fix resolved the "stuck on logo" issue.

Discussion on JC92-025051 Board Replacement

Community members inquired about the JC92-025051 board, questioning its purpose and cost. Some found replacement boards at a relatively high price, prompting concerns about the overall value of fixing the printer.

Advanced User Diagnosis Using RS232 to TTL Interface
