History of WCP 412 firmware Date Version (DD/MM/YY) F/W Emulation Engine 08-30-2001 V0.993 PCL6 2.32 0.98 08-10-2001 Content 1. Fixed Rx journal problem When memory full state is occurred during receiving fax, sometimes comm error is registered at rx journal instead of memory full. 2. Fixed lock-up problem during copy process. The machine is locked up after execution of notify toner low action when copy job is being processing.(found at CVT test) 3. Fixed Image expand problem When memory transmission with standard mode, transmitted image is expanded vertically about 6mm. 4. If the document can’t reach scan position within certain period, pick up the document one more to avoid document jam. 5. Engine Version Up The backside contamination problem at the beginning of LL environment. Sometimes the backside contamination problem is occur at the NN environment. Added high altitude mode. Date Version (DD/MM/YY) F/W Emulation Engine 09-01-2001 V0.994 PCL6 2.32 0.98 08-10-2001 Content 1. Fixed PCL6 error in USB mode. (found at CVT test) 2. Modified some messages in help list. Date Version (DD/MM/YY) F/W Emulation Engine 09-07-2001 V0.995 PCL6 2.32 0.98 08-10-2001 Content 1. In case of toner low state, the machine transmit this state to call center only once. 2. Added drum count reset feature. In the MAINTENANCE menu, if select [NEW DRUM] and select YES then drum count will be cleared automatically. 3. When run scan to memory during receiving fax, received page is disappeared very very rarely. This problem does not appear at normal state, and only appear during dual operation about once per 5000 sheets. 4. Modified help list about drum count reset feature. Date Version (DD/MM/YY) F/W Emulation Engine 09-08-2001 V0.996 PCL6 2.32 0.98 08-10-2001 Content In V 0.995, remote upgrade did not work because we changed the memory allocation method for user memory. To search the free block to store the received data, machine search the free block from the latest written block instead of starting block map so that the fax image is stored the middle of user memory. But our f/w programming task will search the received image in the beginning area of block map. It will be failed to programming. Date Version (DD/MM/YY) F/W Emulation Engine 09-08-2001 V1.00 PCL6 2.32 0.98 08-10-2001 Content There are still data error in dual operation. During the scanning into memory and receiving into memory at the same time, there are still semaphore for both task to allocate The unused block s. This is fixed in file allocation table, page allocation table, block allocation table. We tested this version for 5000 pages scanning and printing at the same time. There is no problem. Also we want to start the Europe Version from 1.00. Date Version (DD/MM/YY) F/W Emulation Engine 09-22-2001 V1.01 PCL6 2.32 1.00 08-10-2001 Content 1.After PC printing in the CCD sleep mode, CCD does not wake up even though CCD waking up activity was executed. 2.Engine version changed. High voltage transfer table is changed at high altitude mode. Date Version (DD/MM/YY) F/W Emulation Engine 10-25-2001 V1.02 PCL6 2.32 1.00 08-10-2001 Content [Several items in the change request are applied.] Changed default value of alarm sound to OFF. (Item 1) Changed default value of key sound to OFF. (Item 2) Changed default value of power save time to 30minute. (Item 4) Changed default level of dial volume to lowest level. (Item 7) Fixed the problem that | is printed as a in the reception journal. (Item 8) Prevent accidental setting of non TBR21 country in Euro machines. (Item 14) Date Version (DD/MM/YY) F/W Emulation Engine 11-21-2001 V1.04 PCL6 2.32 1.00 08-10-2001 Content 1) CEE country would not seen in Select Country in User Mode (item 15) 2) ORIENTATION feature was added.

In CEE LIU( item H5) 10) DTMF level is to be adjusted in Hungary in CEE LIU( item H6) Date Version (DD/MM/YY) F/W Emulation Engine 11-30-2001 V1.05 PCL6 2.32 1.03 08-10-2001 Content 1) Preventing First Page Back-pollution is adjusted 2) Below printing of Front part of page is adjusted when after No Paper 3) Standard Fuser error check is applied. 4) Top margin is adjusted for LSU reflection Xerox Release version has USB scanning problem. But In Production Line, We fixed it and with same version Date Version (DD/MM/YY) F/W Emulation Engine 12-3-2001 V1.06 PCL6 2.32 1.03 08-10-2001 Content Update Version from 1.0.5 to 1.0.6 from Production Line version. Date Version (DD/MM/YY) F/W Emulation Engine 3-29-2002 V1.08 PCL6 2.32 1.07 08-10-2001 Content 1. Change Request List # 27 - The value which is related with COPY is changed to default after preset time. The preset time is optional and can be set in SYSTEM DATA. 2. Change Request List # 28 - The left/right margin of printing area is optional. This function can be worked only in the tech mode. 3.

The image quality is tuned in copy mode. 7. To compensate dust in the shading sheet, the shading is performed in the two position and select the better one of the two shading profile. ------Engine ----- 1.If set a cardstock in Driver, then Transfer voltage is according to Thick type, Printing speed and Fusing temperature are Envelope type. 2.If set a userpaper(width : under 190mm) in Driver, then Transfer voltage and Fusing temperature are according to Setting type in Driver, Printing speed is Envelope type. 3.The blank paper image printing is 4.Changed printing speed for envelope Old : The beginning : 8.5ppm Continuous print on specification point in time : 6ppm New : The beginning : 6ppm Continuous print on specification point in time : 4ppm modified.
