===615n series ASIC issue===
In 2002 HP released the 615n series of Internal EIO print server. This model featured a new chipset manufactured in Singapore that had a problem related to either overheating or data overload. Otherwise known as the ASIC issue, this meant the 615n card could fail without warning, and when it failed, would completely shut down, appearing to vanish from the printer entirely.

Soon afterwards, HP began to do a per-item replacement policy that has ended as of October 31, 2008, when all known 615n cards were at least 4 years old and at such time HP felt it had taken appropriate corporate responsibility for a defect in manufacturing.

The 615n cards most often affected were the units installed in the Laserjet 2300, 4200 and Color 4600 series. Those cards appear to be most prone to failure.

Any 615n series card can fail, but it is up to HP to determine if the failure is due to the chipset or some other factor. HP recommended to call them or contact them through the Web site and they will proceed to do some simple troubleshooting steps to determine if the failure is due to the chipset or some other cause.<ref>{{cite web|url=http://www.hp.com/pond/jetdirect/j6057a.html |title=HP J6057A 615n EIO 10/100 Information |access-date=February 2, 2016 |url-status=dead |archive-url=https://web.archive.org/web/20110609014450/http://www.hp.com/pond/jetdirect/j6057a.html |archive-date=June 9, 2011 }}</ref> If it is proven to be the chipset, HP would be able to replace the card under warranty with an as-new card (nominally a 620n).
