Problem Description: Out of memory failure.

Corrective action:

It is recommended that you remove any unnecessary files from the Hard Disk Drive of the Formatter using the Web Server.

System Error: 71:04 (T610 printers ONLY)

Problem Description: Out of memory failure. The total RAM memory available in the HP Designjet T610 Printer Series is 128MB. If the amount of memory that the printer needs to process the file is more than 128MB, the printer will display the system error 71:04 System Error (“Out of Memory” message). This quantity of memory for processing the file is know as the ‘Display list memory’: ; The display list memory is the amount of memory that the printer needs to process a file, this should not be confused with the file size of the print job, which is different. The size of the display list memory depends on several variables such as the resolution, file size and file content. ; The display list is not visible to the user. ; There has been a few cases where a print job that had a relatively small file size has triggered an out of memory message to be displayed. Print jobs like this typically have a large number of objects in them or have complex objects such as raster images with gradients or objects with multiple layers. Any print job that contains these type of images can result in a display list memory greater than 128MB.

Corrective action: Try the following:

1. It is recommended that you remove any unnecessary files from the Hard Disk Drive of the Formatter using the Web Server.

2. It is also recommended that you upgrade the firmware to the latest version available at www.hp.com.

3. Decrease the print resolution to 300 dpi If the customer does not accept the print quality after reducing the resolution or using Econofast printmode, proceed to the workaround in step.

4. The resolution required by the printer to process the file is set by printmode selected (Best, Normal, Fast). There is a setting available that enables you to decrease the resolution for each printmode to 300 dpi. If this setting is used, the rendering resolution will be reduced, but the output (printing) resolution will remain the default of the selected printmode There could be an impact on Image Quality because of the reduction in the rendering resolution, this will be especially noticeable in circles and lines with very low inclination.

5. Use ‘Econofast’ printmode. The rendering resolution will be selected by default to 300 dpi. From the Printint Preferences pane, select custom options and then settings. In the Custom Print Quality Options pane, select Economode. If the Out of Memory message still persists, proceed to the next workaround.

6. Out of Memory issues can always be solved if the processing of the job can be performed before reaching the printer. This can be done by selecting ‘Send Job as Bitmap’. The main processing of the print job will then be performed by the computer. This means that more computer resources can be used to process the plot. This form of printing is recommended in the case where the print job contains raster images plots, and mixed plots with raster images and lines, this is because the process of turning the print job made of raster images to vector images leads to a significant increase in the display list size.

System Error: 71:19

Problem Description: Default Serial Number found in the main and backup NVM. It seems that both the Formatter and PrintMech PCA (T1100/T1100ps/ T610) or Media Advance Encoder PCA (T1120/T1120ps) have been replaced together, or a previously used Printmech PCA or Media Advance Encoder PCA was installed.

Corrective action: Try the following:

1. Perform the Error 71:19 Recovery Service Utility. More information: Unauthorized upgrades To prevent unauthorized upgrades of printers to a superior model, the new firmware has changed the initialization process of the printer. Location of the Serial and Product numbers The serial number and the product number information is stored in two locations, in the EEROM of the Printmech and the EEROM of the Formatter. Old initialization process

2. In the previous initialization of the printer, the serial numbers and product numbers were compared in the EEROM of the PrintMech PCA (T1100/ T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps) and the ERROM of the Formatter. If there was a difference, the printer displayed SE 71:19.

3. The 71:19 recovery procedure could then be performed. This enabled anyone to do one of the following, possibly resulting in an unauthorized upgrade:

4. Input a serial number and product number into the PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/ For T1100/T1100ps/T610 printers, the backup NVM is located in the Printmech PCA. For T1120/T1120ps printers, the backup NVM is located in the Media Advance Encoder PCA. In all T Series printers, the main NVM is located in the Formatter service part. You MUST NEVER replace both the Formatter and the PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps) at the same time. If both parts need to be replaced, you MUST first replace one part and then power ON the Printer until it completely initializes. Then you can power OFF the Printer and replace the other part. Never install a previously used PrintMech PCA (T1100/ T1100ps/T610) or Media Advance Encoder PCA (T1120/ T1120ps) into another printer. T1120ps) and Formatter EEROM.

5. Choose which EEROM held the correct information, and copy it across to the other EEROM. New initialization process From firmware 7.x.x.x onwards, the information is now always copied automatically from the EEROM in the PrintMech PCA (T1100/T1100ps/ T610) or Media Advance Encoder PCA (T1120/T1120ps) to the EEEROM in the Formatter. This means that the printer will now take on all the attributes of the information located in the PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps), possibly rendering the printer unusable. The following are just a few examples of why this could be possible.

6. The printer may not be able to fully initialize if there is a mismatch between the size of the printer and the size in the EEROM of the PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps).

7. The PostScript capabilities of the printer could be affected.

8. All the calibrations applied from the factory will be copied, so incorrect calibrations could be applied to the printer. How to resolve serial/product number errors Any issue will need to be escalated through your local support organization if:

9. A reused PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps) has been accidentally installed

10. Both the PrintMech PCA (T1100/T1100ps/T610) or Media Advance Encoder PCA (T1120/T1120ps) and the Formatter have been installed at the same time in error.
