## Abstract

This aritcle presents a method to distinguish papers of different print jobs on a shared printer. This method uses a rotatable paper tray, after one print job completes, the tray rotates a certain degrees horizontally, thus the papers of each job will have an angle of certain degrees with those papers of previous job and next job.

An method to distinguish papers of different print jobs

This invention presents a method of using a rotatable paper tray to distinguish printed papers of different print jobs on a shared printer.

Background:

In general, we share several printers in office to lower per page costs and better support. When multiple users submit printing jobs to a printer at the same time, all printed papers are overlapped, users have to rummage through the papers to find his/her printed papers, this can be a time-consuming task when the number of paper is large, as shown in Figure 1.

Figure 1. All printed papers are overlapped

A commonly known solution is to print a cover page for each job to distinguish papers of different job , but user still need to rummage through the papers to find his/her printed papers, moreover, user may take more or less papers when taking his/her papers from the a bunch of overlapped papers.

Is there any other way to help users to distinguish papers of different print jobs easily and quickly? Our invention provides a feasible way to solve this problem.

In this invention, we present an intelligent method to distinguish papers of different print jobs, this method uses a rotatable paper tray to hold the printed papers. When a print job is completed, the tray rotates 90 degrees horizontally.

Thus the papers of each job will have an angle of 90degrees with those papers of previous job and nextjob, printer user may find his/her printed papers easily, as shown in Figure 2.

Figure 2. Papers are directly cross

In this invention, we only need to modify one place of existing printers. As shown in Figure 3, we replace the paper tray with a

rotatable paper tray. When a new print job completes, the paper tray rotates a certain degrees.

Working process:
When print job 1 is completed, the paper tray rotates a certain degrees(for example, 90 degrees) horizontally. When the papers of

job 2 come out, there will be an angle of 90 degrees between the papers of job 2 and the ones of job 1. After job 2 is completed, the paper tray rotates a certain degrees(for example, 90 degrees) again....
