According to the current standard design of color photo laser printers such as Fuji 550, 570, 590, the maximum printing length of a photo is 45.5 cm (18 inches). Along with people's new pursuit to super long photo, this kind of existing color photo laser printing machine has been unable to apply. Since the color photo laser printing machine is a relatively expensive and complex equipment with a large volume, purchasing new equipment means repeated investment of large sums of money and the problem that the site must be enlarged.

Whether the existing color photo laser printing machine can be used to increase the maximum printing length of a photo through modification is a long-standing problem to be solved in the industry. If the paper cutting time of the paper cutting mechanism is extended by modifying the circuit parameters, the paper box mechanism can output photo paper with extended size, but because the paper feeding speed of the paper box mechanism on the color photo laser printer is slightly higher than the paper feeding speed of the exposure device The paper feeding speed of the exposure device is slightly higher than the paper feeding speed of the developing device. When the length of the photo is within the maximum printing length limit of the original standard design, the various parts of the color photo laser printing machine can be complemented and coordinated without machine jams. However, when the length of a piece of photo paper exceeds the design standard length, the complementary coordination functions of each part of the machine cannot be digested, and paper jams will occur. Therefore, the existing color photo laser printing machine is modified to increase its photo. The subject of the maximum print length has not yet been resolved.
