Detailed Service Note
Content

Situation
Customers will request the 8MB DIMM since the data sheet shows that the model comes with this memory, but it was not installed in the initial shipped products.
Action
To Be Performed By: Customer: Install the 8MB DIMM when it is shipped to them. The US and the European CCC’s can CREW the part to the customer. AP CCC’s can POP the part out to them. If there is a less costly method than CREW or POP that a country/region employs to get parts out to a customer, please use this method. If there are not CREW or POP abilities in a country/region, please have the customer use the standard warranty method to have it upgraded. Labor can be used at .25 hours.
Additional Information
Please have the customer contact their local Customer Care Center to have the DIMM ordered for them. These centers can be found at this web site, just select your region: http://www.hp.com/cpso-support/guide/psd/expectations.html
CCC Centers: If you have a customer with many of these products (100 or more), please escalate to division for assistance in ordering larger quantities of the DIMM. If some of those customers are unwilling to install the DIMMs themselves, please escalate to Division for assistance.
Please advise customers to take care when handling the DIMM. Do not handle the DIMM by the connectors (gold fingers), and unplug the printer or turn it off (220V only) before installing the DIMM.
Note: There is no performance degradation without the additional DIMM. The additional memory will assist in handling more jobs sent to the printer due to the additional memory storage.
English instructions for installing DIMM are attached (taken from the Users Guide):
If you add memory (RAM only) to the HP LaserJet 1200, you can print more complex print jobs.
To install a DIMM, follow the instructions below:

CAUTION |
Handling a DIMM chip (memory) without wearing a grounded, antistatic device might damage the DIMM chip. |





To test the DIMM installation, print a configuration page and check the Memory Available specified on the page. See Printing a configuration page for more information.
If the DIMM installation was unsuccessful, see Printer light patterns for DIMM troubleshooting steps.
