4 Software (Situation Code: s.1) The Computer with the Perfactory Direct software module cannot connect to the Perfactory machine via Ethernet. 1. Look at you network parameters of your PC/ network IP address of the Perfactory should only differ in the last digit. Make sure that the selected IP adress is ONLY for the Perfactory and no other computer in the network has the same. Also, both IP addresses are using the exact gateway submask (ie: ). The subnet mask numbers should match exactly. 2. Ensure you are using the correct cable to connect the machine: a) Use at least a type Cat 5 cable which is double screened. b) Check that you are using a cross over cable if it is a direct connection between the computer and the Perfactory, or a patch network cable if the Perfactory is on a network. c) The cable length should be smaller than 10 m. 3. Check to make sure that the correct cable use is not defective and fully snaps into the socket at the computer and the Perfactory PC. 4. Try to use the ping command to see the Perfactory machine from the Pre-processing computer: a) Go to "Start" at you windows system (Bottom lefthand corner) b) Select "programs" c) Select "accessories" d) Select "command prompt" e) In the text box type the following at the prompt "ping <ip address of Perfactory machine>" f) After entering the command the PC will try and contact the machine directly. If the response is "destination host unreachable" the test has failed. A positive response will result in the following text appearing "reply from <ip address>: Bytes=32" 5. Make sure that you rebooted the Perfactory or the pre-processing computer after you entered a new IP address or a Submask for the changes to take effect. Software (Situation Code: s.2) The Perfactory machine is connected to the PC under "Perfactory Direct", but when we "add job", I can see the job on Perfactory Direct, but when I push the orange start button on the machine keypad, the message " NO JOB FOUND" appears. Go to Network settings. Do not make any changes to the IP address or the submask. Push Enter when prompted to reboot the system, and try sending the job again Troubleshooting Guide Preliminary Issue 4/2004

5 Projection Unit (Situation Code: p.1) After installing a new light bulb, it is not possible to achieve the brightness level which could achieved if the previous light bulb is re-installed. 1. Remove the light bulb and look through the hole at the yellow filter to see if there is a problem with the glass filter such as cracking or milky spot at the entry point of the light. If yes, please contact your local service provider to change that glass filter. 2. If you go to projector brightness and adjust the level from minimum of zero to a maximum of 200, then the power measured should also change, other wise increase the lamp power by 10% and try again in 5 minutes, then you should see a change in the power when adjusting the brightness. If you do not see a change, then the pc-board is defective. Please contact your local service provider to change the board. Projection Unit (Situation Code: p.2) After installing a new light bulb the projector will not ignite.
