The encoder strip should be cleaned when requested by the printer. The front panel displays a message when cleaning is required: For optimal printer performance follow the Clean the encoder strip process as described in the User Guide. NOTE: When the message is displayed on the front panel, a silent warning message is added within the system error log '8:01'. This helps when reviewing the error log history. Cleaning procedure 1. At the front panel, press , then Preventive maintenance tasks > Clean scan axis encoder. 2. Open the window. 3. Clean the encoder strip on both sides with a cloth dampened with water, as instructed in the front panel, and press Continue when finished. 4. Close the window. The carriage moves to the left-hand side of the printer. 5. The front panel prompts you to reopen the window and clean the right-hand side of the encoder strip (inside the service station). Press Continue when finished. 6. Close the window. The carriage returns to its ready position in the service station. Clean the platen You should clean your print platen after every 40 liters of ink used (the front panel will remind you with an alert), and additionally when you notice any of the following symptoms: ● Ink smearing when printing with presets that used to work well (vacuum loss) ● More frequent substrate jams ● Ink stains and marks on the back of your prints ● Advance issues even when using the substrate-advance sensor NOTE: If you print on wide substrate after having printed on narrower substrate, you may find that the left side of the platen has become dirty. If this contaminated section of the platen is not cleaned, it could leave marks on the back of the substrate. NOTE: Do not print on porous substrates when using the platen, as it will get dirty. Use the ink collector for porous substrates. NOTE: If, when cleaning the platen, you see that any sticker is missing or out of place, you can replace it with one of the spare stickers provided in the User Maintenance Kit. CAUTION: Be careful not to damage the substrate-advance sensor when cleaning the platen. The sensor is the very small rectangular window (less than 1 cm²) found close to the third pinchwheel from the right. See Clean the substrate-advance sensor window on page 167. TIP: You are recommended to wear gloves. Follow these instructions to clean the platen. 164 Chapter 7 Hardware maintenance ENWW
