• Code: 41.5
• Display: 41.5 UNEXPECTED TYPE TRAY X
• Description: Tray (X) is loaded with media that is not of the same type configured for the tray. Note The printer only detects media or OHTs.
• Remedy: 1 Check the media type definition for the specified tray. 2 If necessary, reconfigure the media type for the tray. 3 If the error does not clear, turn the printer off, and then turn the printer on again. 4 If the error persists, check the transparency sensor for correct functionality. Check connector J3032 on the transparency sensor, intermediate connector J3027, and connector J121 on the DC controller PCA.

• Code: 41.X
• Display: 41.X PRINTER ERROR
• Description: A temporary printing error occurred.
  X description: 1 = unknown misprint error 2 = beam detect misprint 3 = media feed error (size) 5 = media feed error (type) 6 = ITB detection error
• Remedy: 1 Press GO to clear the error and continue printing. 2 Turn the printer off, and then turn the printer on again to clear the error. 3 If the error persists, troubleshoot the laser system (41.2), the media feed mechanisms, the media size/type settings, and the ITB seating.

• Code: 49.XXYY
• Display: 49.XXYY PRINTER ERROR
• Description: A critical formatter firmware error occurred which caused the processor on the formatter to cease operation. Note Unique subcodes are constructed by creating a unique error of an 8-bit component ID (XX) and an 8-bit component specific error (YY). The component ID and component specific error are useful in determining which part of the firmware failed.
• Remedy: Note The printer 49 errors are usually not fixed by replacing the formatter. 1 Turn the printer off, and then turn the printer on again to clear the error. 2 Make sure that the customer is using a known good software program, good driver, good cabling, and good connections. 3 Print a configuration page to make sure that the printer has the most recent release of formatter firmware. If necessary, flash the printer with new firmware. 4 Check all of the accessory hardware, such as memory DIMMs and EIO devices, on the formatter by removing them. (Removing the hardware eliminates them as possible causes of the error.) 5 If the error persists, the formatter might need to be replaced.

• Code: 50.X
• Display: 50.X
• Description: A fuser error occurred. Power cycle the printer to continue.
  X description: 1 = low fuser temperature 2 = fuser detected not coming to operating temperature after a jam or open door 3 = high fuser temperature 6 = open fuser heating circuit between the fuser and low-voltage power supply 7 = fuser pressure release mechanism failure
• Remedy: 1 Remove the fuser and check it for damage or jammed media. 2 Make sure that the printer is plugged into appropriate ac voltage. 3 Turn the printer off, let it cool for 10 minutes, and then turn the printer on again to possibly clear the error. 4 Replace the fuser. 5 Check the fuser/print engine electrical connectors J3019 for damage. 6 Check connector J1501 on the fusing sensor PCA and connector J115 on the DC controller PCA. 7 Check for a fuser drive or fuser motor failure. Replace if necessary. 8 Replace the power supply unit. 9 Replace the DC controller PCA.

• Code: 51.XY
• Display: 51.XY PRINTING ERROR
• Description: A laser scanner assembly laser error occurred.
  X description: 1 = beam detect error 2 = laser error Y description 0 = no color K = black C = cyan M = magenta Y = yellow
• Remedy: CAUTION When servicing the printer with the top cover off, cover the top of the printer to prevent light leaks which might blind the laser/scanner beam detect sensors. 1 Check the FFCs for damage, and make sure that they are correctly centered and seated in the connectors. Replace the FFCs if necessary. 2 The following are color-specific steps: • K laser Check connector J3012 on the laser driver PCA, connector J3056 on the scanner motor, connector J3061 on the beam detect PCA, connectors J812 and J815 on the T driver PCA, and connector J110 on the DC controller PCA. • C laser Check connector J3011 on the laser driver PCA, connector J3059 on the scanner motor, connector J3062 on the beam detect PCA, connectors J812 and J815 on the T driver PCA, and connector J110 on the DC controller PCA. • M laser Check connector J3010 on the laser driver PCA, connector J3053 on the scanner motor, connector J3063 on the beam detect PCA, connectors J812 and J815 on the T driver PCA, and connector J110 on the DC controller PCA. • Y laser Check connector J3009 on the laser driver PCA, connector J3050 on the scanner motor, connector J3064 on the beam detect PCA, connectors J812 and J817 on the T driver PCA, and connector J108 on the DC controller PCA. 3 Check FFC connectors J103 and J106 on the DC controller PCA, J9002 on the formatter cage, and J801 on the T driver PCA. 4 Replace the necessary laser scanner unit. 5 Replace the T driver PCA. 6 Replace the DC controller PCA.
