Why can't I send my document?
All documents in the "Send Preparation" are categorised as "Ready for sending", "Action required" or "Not available for sending".

Documents in the category «Ready for sending»:
The category "Ready for sending" lists all documents that are directly available for sending. The "X" on the right-hand side can be used to remove documents from the list (and thus from the sending) if necessary. Only the documents listed in this category will be submitted for sending.

Unable to process PDF document
These documents cannot be processed by Pingen. Please ensure that the PDF-files are not corrupt or protected and try again.
Pages in invalid paper format
Pingen only supports sending documents in format A4 portrait. The affected documents are often either in format US Letter (215x279mm) or contain pages in format A4 landscape (297x210mm). Make sure that all pages are in format A4 portrait (210x297mm) and upload the documents again.
PDF no longer exists for privacy reasons
These documents have already been removed from Pingen for data privacy reasons and can therefore no longer be sent. If these documents are still to be sent, they must be transferred to Pingen again.
Exceeds file size limits
These documents exceed the maximum size of 8 MB. PDFs larger than 8 MB must be compressed before uploading. There are free online tools such as smallpdf that offer PDF compression.
File not Found
These documents are invalid and were not stored in Pingen. To send such documents, they must be recreated in accordance with Pingen's requirements and re-submitted.
PDF contains form fields
Pingen cannot be used to send documents with form fields. Remove the form fields from the PDFs (e.g. via AvePDF) and upload the documents again.
PDF contains annotations
PDFs with annotations cannot be sent via ping due to technical reasons. Remove the annotations (e.g. via AvePDF) from the PDFs and upload the documents again.
Invalid PDF Binary Content
The PDF standard specifies that the binary content of PDFs must begin with %PDF-{PDF standard version}, e.g. %PDF-1.7, and end with %%EOF. Documents with the remark "Invalid PDF Binary Content" have a binary content that is not structured according to the PDF standard.
Important: The binary content of the document can be viewed when the PDF is opened in a professional text editor such as UltraEdit or SublimeText:

Not available for sending
These documents are incompatible with our requirements and have properties that cannot be fixed by Pingen. Therefore they cannot be sent via Pingen.
Documents belong to a batch
![Letters cannot be sent individually](https://cdn.prod.website-files.com/61796737927c5486381824f7/6459f197f51d6347501b0a1e_batch-briefe-einzeln-versenden.png)
A batch is automatically created as soon as a continuous PDF or ZIP file is uploaded. Letters within a batch are handled as a group and cannot be sent individually. To send these letters, the entire batch must be submitted for sending. More information about letters within a batch can be found here
