Method of cleaning ink remaining on photoreceptor web when error occurs in printer

A method of cleaning ink remaining on a photoreceptor web when an error occurs in a printer including a development unit for supplying ink to a rotating photoreceptor web to develop an electrostatic latent image formed on the photoreceptor web, a charger for charging the photoreceptor web to a predetermined level of electric potential, a transfer roller for transferring a toner image formed on the photoreceptor web to a sheet of paper, a drying unit for absorbing and vaporizing liquid carrier remaining on the photoreceptor web, and a cleaning roller installed to clean the transfer roller, the method comprising the steps of:

• (a) stopping a printing operation when an error occurs during the printing operation;
• (b) transferring the ink adhering to the photoreceptor web to the transfer roller by rotating the photoreceptor web a predetermined number of times in a first state in which the cleaning roller is separated from the transfer roller and the transfer roller contacts the photoreceptor web;
• and
• (c) removing the ink transferred to the transfer roller in a second state in which the cleaning roller contacts the transfer roller when step (b) is completed.
