CITIZEN 1/38 iDP-3535 User's Manual IMPORTANT SAFETY INSTRUCTIONS s Read all of these instructions and save them for later reference. s Slots and openings on the cabinet and the back or bottom are provided for ventilation. To ensure reliable operation of the product and to protect it form overheating, do not block or cover these openings. The openings should never be blocked by placing the product on a bed, sofa, rug of other similar surface. [. . . ] Any printing without paper and ribbon cassette may cause damage to printer head. 3) Be careful not to drop any foreign matters, such as paper clips, pins and the like into your printer. 5) Always place your printer on a stable desk which is set horizontal. 6) No organic solvent (thinner, benzene or the like) should be used in cleaning the surface of the main body case. 7) Make sure that the power of the printer is turned off whenever you do the following. 8) Please use Cash Drawer connector (CN 6) for drive Cash Drawer only. For U-type (USA type) Do not use Paper winder and Cash Drawer with connectors (CN 6-2 and CN 3-2) at the same time. USAGE OF THE CONNECTORS, PLEASE SEE PAGE 18 AND 19.

Signal level of these points (Mark = 1, Space = 0) are read as input data. The sequence of these bit is Bit 0, Bit 1 ~ Parity bit from Start bit. 3) Stop bit The stop bit consists of one or more bits at "mark" level. When "space" level is detected for a stop bit, a framing error occurs. CITIZEN 19/38 iDP-3535 User's Manual 5-5 Error Detection The printer detects Parity, Framing and Overrun Error. Framing Error; Framing error occurs when SPACE signal is checked out at STOP BIT and the printer print out (7FH). Parity Error; Parity check is carried out only when user designates it on the printer pre-setting. Input Control and Buffering; (over-run-error) The printer is designed to output DTR signals for each word. If the host computer neglects DTR signal and transmits the data, it may cause the "OVER-RUN ERROR". [. . . ] When the input data become full to fill one line, the Full Buffer Print and one line feed will be automatically carried out. The same function as RS is performed by SO code (except for serial 7 bit data use). (3) Red Color Print Mode Designation DC (12) DATA LF (0A) All print data including DC2 are printed in red color and it's not possible to mix the black and red color characters on one line. If DC2 commands are used 2 times on the same line by error, the printer will print out all characters in black color. [. . . ]
