3.9.2 Sensors and printing When the printer detects a paper near-end, it either stops or continues printing depending on the ESC c 4 setting. The corresponding sensors are as follows: Journal near-end sensor Receipt near-end sensor Journal sensor Receipt sensor Slip insertion sensor The journal near-end, receipt near-end, journal, and receipt sensors are enabled only in two-sheet mode and the slip insertion sensor is enabled only in slip mode. However, since the journal and receipt sensors are used for auto-loading and cannot be used for paper-end detection, the end of paper is not detected by them. The user should note that these sensors may not stop printing, even if they are selected by ESC c 4. Therefore, use the near-end sensor for detecting a roll paper-end, and also use the paper sensor, if necessary. The printer behaves as follows in the paper-end state: 1) Two-sheet mode When printing stop is enabled, the printer automatically goes off-line when a paper-end is detected. To restart printing, load the paper and set the printer back on-line by closing the printer cover. 2) Slip mode When printing stop is enabled, the printer detects a paper-end and prints data up to the end of the printable area, ejects the slip, and then waits for the slip to be removed. After the slip is removed, the printer enters the paper waiting state. 3.10 Printer Cover 3.10.1 Cover open button When the cover open button (see Section 5.3, External Appearance) is pressed, the printer cover is opened. When the cover is closed, the cover open button is latched. NOTE: Be sure to use the cover open button located on the front of the printer to open the printer cover. 3.10.2 Cover open sensor The cover open sensor monitors the printer cover. When the sensor detects a cover-open, the printer automatically goes off-line after printing the current line. After the printer cover is opened, the printer moves the carriage to the home position at a low speed. To get back on-line, close the printer cover. NOTE: Because the printer mechanism is reinitialized after the printer cover is opened and closed, the cover must not be opened during printing to prevent an incorrect paper feed pitch.
