Code: 1-092
Description: When xerographic paper is used in ADF, ghost occurs at 94mm intervals
Causes: Engine board. The (+) transfer voltage may be abnormal when performing DCU 13 with 100 Mohm load on the transfer voltage output. (Normal voltage: 900V (+5/-5V) DCU 14, 1450-1550V DCU 13).
Remedy:

Code: 1-093
Description: When printing on card stock or transparencies using manual feeder, ghost occurs at 94mm intervals
Causes: 1. Improper paper type selected in menu setup 2. Engine board.1. When printing on card stock or transparencies, higher transfer voltage is required. Select Thick mode on paper type menu using panel or software application. 2. Defective transfer voltage circuit in the engine board.
Remedy: 1. Select Thick Mode on paper type menu using panel or software application to print on card stock or transparencies. 2. If the transfer voltage circuit in the engine board is out of specification, refer to Error Code 1-091

Code: 1-094
Description: Ghost occurs in printing at 56mm intervals
Causes: Fuser. The heat roller and pressure roller in the fuser are contaminated with toner or paper particles.
Remedy: Open the rear cover and check if the heat roller is stained. If stained, disassemble the fuser and clean the rollers with a soft cloth dampened with alcohol. If ghost still occurs, replace the fuser.

Code: 1-095
Description: White ghost occurs in the black image printing at 94mm or 46mm intervals.
Causes: 1. Developer cartridge 2. Engine board. 1. The life of the developer may expired. 2. Abnormal transfer voltage.
Remedy: 1. Measure the weight of the developer and replace if the weight is less than 1000g +/-20g. 2. Check the transfer voltage and adjust if necessary.

Code: 1-100
Description: Partially blank image, either periodically or non-periodically.
Causes: 1. Transfer roller 2. Developer cartridge. 1. Unequal pressure on the left and right transfer roller springs; the springs are damaged; the transfer roller is improperly installed; or the transfer roller bushing or holder is damaged. 2. If a black image prints light or gradually becomes light at intervals of 47mm, the transfer roller is defective. 3. If there is a partial blank image on left and right side of the page: 1) The life of the transfer roller has expired. 2) Abnormal transfer voltage. 3) The life of the developer has expired.
Remedy: 1. Replace the defective components. 2. Replace the transfer roller. 3-1. Replace the transfer roller. 3-2. Measure the transfer voltage. If the voltage is abnormal, disassemble the main board and clean the components stained with toner or paper particles. 3-3. Measure the weight of the developer. If the weight is less than 1000g, replace the developer.

Code: 1-110
Description: Background too dark
Causes: 1. Developer cartridge 2. Main body. 1. Toner leakage due to improperly sealed developer. 2. Transfer roller length out of spec. (216.5 mm) 3. The inside of the unit is contaminated with toner or paper particles.
Remedy: 1. Clean the unit thoroughly. If problem still occurs, replace the developer. 2. If the roller is shorter than the recording paper or severely stained, replace. 3. Clean contaminated components

Code: 1-120
Description: Blank page is printed.
Causes: Bad ground contacts in OPC and/or developer. 1. Bad ground contacts in OPC and/or developer. 2. Improper OPC ground connection.
Remedy: 1. Clean the contaminated contacts 2. Open the cover and check/repair the connection
