SC-T7630D/SC-T5630DM User's Guide Introduction ❏ If you do not print for a long time, the print head nozzles may become clogged. We recommend that you print once a week to prevent the print head from clogging. ❏ Do not operate with sharp objects such as ballpoint pens or mechanical pencils. Doing so could damage the control panel. ❏ If the panel gets dirty, wipe it with a soft cloth. If the panel is particularly dirty, dampen the cloth with water containing a small amount of neutral detergent, firmly wring the cloth dry before using it to wipe the panel, and then finish by wiping with a soft, dry cloth. Never use volatile chemicals such as thinner, benzene, or alcohol.
Doing so could damage the surface of the control panel. ❏ The roller may leave an impression on paper that is left in the printer. This can also cause wavy or curled paper resulting in paper feeding problems or the print head could be scratched. Remove any paper when storing. ❏ Store the printer after confirming that the print head has been capped (the print head is positioned at the far right). If the print head is left uncapped for a long time, the print quality may decline. ❏ Do not use in an environment that is subject to sudden changes in temperature or humidity. Condensation may form inside the panel, causing a decline in performance. Note:
If the print head is not capped, turn the printer on, and then turn it off. ❏ Some pixels on the screen may not light up or may light up constantly. Also, due to the characteristics of the liquid crystal display, uneven brightness may occur, but this is not a malfunction. ❏ To prevent the accumulation of dust and other foreign matter in the printer, close all covers before placing it in storage. If the printer will be not be used for an extended period, protect it with an anti-static cloth or other cover. The print head nozzles are very small, and they can become clogged easily if fine dust gets on the print head, and you may not be able to print properly.
Notes on Handling the ink supply unit ❏ Store ink supply units at room temperature out of direct sunlight. ❏ When turned on after an extended period of disuse, the printer may automatically perform head cleaning to ensure print quality. U “Print Head Maintenance” on page 146 ❏ To ensure print quality, we recommend using all of the ink before whichever of the following dates is earlier: ❏ The recommended expiry date shown on the ink supply unit packaging ❏ When moving, transporting, or storing the printer in an environment below -10˚C, contact your dealer or Epson Support.
❏ One year from the date the ink supply unit was installed Notes when using the control panel ❏ Ink supply units that have been stored at low temperatures for an extended period should be allowed to return to room temperature over a period of four hours. ❏ Touch the panel with your finger. It will only react when you touch it with your finger. ❏ The ink level and other data are stored in the IC chip, allowing ink supply units to be used after being removed and replaced. ❏ It may not react when operated with something other than a finger, when operated with wet fingers or gloved hands, or when operated when there is a protective sheet or sticker on the panel.
❏ To avoid getting dirt on the ink supply port, store the removed ink supply unit properly. The ink supply port has a valve in it so it does not need to be capped. 19
