目前在我国使用的许多计算机系统中,都配有美国生产的2230型宽行打印机。该机功能比较齐全、性能比较稳定,设计也比较合理。但在实际使用中,我们发现其垂直格式走纸装置VFU的格式带读出器欠佳,该读出器几乎是全机械结构,这不仅有碍于维修,而且由于机械本身的误差及长期磨损,往往导致读带失误而使整机不能正常工作。严重时,甚至反复重启动很多次才能偶然选准一次。这样无形中使本来就较少的进
Many computer systems currently used in our country are equipped with 2230 wide-format printers manufactured in the United States. The machine features a more complete, more stable performance, the design is more reasonable. In practice, however, we found that the format of the VFU with its vertical format was poorly equipped with a read-out reader that was almost fully mechanical, which not only hindered maintenance, but also caused mechanical errors and long-term wear , Often lead to read errors with the machine can not work properly. In serious cases, even repeatedly restart a lot of times to accidentally selected once. Invisible so that has been less into
